We do not have any special email address for inquiries and the only way is to use our Contact Form.
All messages from addresses that are not on our whitelist will be rejected, even if you try emailing directly to our staff or to the email address shown in our web pages written in Japanese.

It will not be accepted if the sole purpose is to carry out a price survey.

We specialise in compounds that are not available elsewhere. We would decline and recommend that you do business with the other partner if your purpose is to compare prices with other companies.

If you need significantly more than the quantity we have indicated on our pages, we can quote you the price of our maximum capacity (approximately 10 times the shown scale shown on the page:SCHEM00403 or in milligram scale if not shown in the page.) because of our facility limitations.
The price we can currently quote for the quantity you require is a multiple of the maximum quantity price.
If you place an initial order within the maximum amount, we will be able to consider scaling up to your desired amount within the range of the initial service.
You may then be able to get a more realistic price from us for the quantity you need.
In the first small scale order, you have the advantage of being able to confirm the stability of this compound during transportation and the quality of our services.
In case you need the price for your desired quantity without the steps we have outlined, please provide your target price.
We have never had an order placed by someone without a budget quote. If you have not thought about this borderline, we judge that you have no intention of ordering at all from the start.
We will therefore make the quote conditional.
We will consider and answer your question based on whether it can be done within the budget you provide.
If your budget is reasonable, we might be able to suggest specifications that fit within your budget.
This could be achieved by for example, reducing the purity of the warranty or suggesting less expensive alternative structures.
In any case, our lab. equipment does not allow 100g or larger scale in single batch operation.
If you are in a special circumstance, please be sure to specify the background in the remarks section of the enquiry form.

Exporter is not responsible for any regulation in your country nor shipping back of the product caused by the prohibition and limitation.

For the first-time dealing, we accept payment upfront only.
We can accept other methods such as bank transfer, but PayPal payment is highly recommended.

The PayPal procedure is as follows.

1) To your offer via this contact form in this page, we will send a reply mail showing the price, lead-time, and notes, if any.

2) If you can approve the price and make clear of the cautions shown in this page, especially the import regulations, please order by an e-mail including the shipping address, phone number and the name of the receiver.

3) When we finish synthesis, purity check and be ready for shipping the ordered compounds, we would report the COA of the submitting lot.

 We will report LC-MS and HPLC data in the COA. Details vary with each compound.

4) Please place an official order by an e-mail if the purity and MS spectrum data are acceptable.
¹H-NMR analysis need extra three weeks lead time and 115,000 JPY separate fee.
NMR analysis includes removal of the solvent, re-purification (if needed), LC/MS reanalysis of the recovered sample.
The NMR analysis fee can be reduced to 45,000 JPY if 2-3mg loss of the NMR sample, by skipping the recovery procedure, is permitted.

5) You will receive an e-mail from PayPal asking for payment.

6) After confirming the deposit of the billed amount (your PayPal payment can be confirmed at the same time as the payment process) we would ship the compounds by FedEx within 48 hours.

7) We will inform you of the tracking number of the shipped compounds.

Bank accout transfer is also available if PayPal payment is inconvenient for your institute.
We will ship the product as soon as we confirm your payment.

Our bank account details are as follows;
Bank Name:Sumitomo Mitsui Banking Corp. Nishinoda branch.
Bank Account:119-6956744
Bank Code:0009
BIC/SWIFT:SMBCJPJT XXX
No IBAN Code.

Please note that it usually takes several weeks or more confirming the deposit.
Over the past few years, Japanese banks have become very strict about receiving payments from overseas.
We will be asked to submit documents at every deposit regarding the breakdown of the payment
and the purpose of the deliverables, and in some cases even refused to accept the payment.
PayPal, on the other hand, is much smoother and no screening process occurs when making deposit.
In any case no refunds will be made for deposits made by bank transfer, PayPal is refundable in a simple procedure.

Wise(TransferWise),Square would be also available.
 We have not experienced these usefull services yet, but we will give it a positive consideration.

At this time, it is difficult to accept Bitcoin as a payment method.

We never accept "Payment on delivery" nor "Pay later" in any case. We apologize there is no room for negotiation about this.

We exclusively sell our products to overseas customers who trust us and can pay in advance.

After the second time (means proved to be a trustworthy client for us), we will be open for negotiation on payment procedure. Later pay could be one of the choise then.

We are sorry, but please note that there is a surcharge for customers on their first transaction which is treated as a deferred payment due to some special circumstances.

If kept cool, the risk of decomposition would be reduced significantly but...

We usually ship our compounds in room temperature considering the balance of cost between risk.
Keeping cool until arriving with dry ice is available by 120,000JPY (very expensive!) additional charge.

We might be able to recommend you to order smaller amount (less than one milligram) for the first purchase to minimize finantial risk.

Our QoS can be assessed and can make clear the stability and the risk of this compound's decomposition during transportation.

Disadvantages are that it makes the total price relatively high and takes longer term obtaining the required total-quantity.

We will ship by default with FedEx (Federal Express) normal shipping unless a customer specifically indicates a different carrier. A fee of $2,000 is required for shipping by refrigerated or frozen delivery. Shipping cost out side Japan shall be quoted at the time of your inquiry when it is required. Any tax out side Japan is not included in our quoted price.
Our incoterm is DDP.

All our compounds are for "Laboratory Use Only".

Structure of the compound is confirmed by LC/MS, GC/MS, and/or TLC data.
We make comprehensive decision based on our extensive experience at all the time.
NMR analysis is performed only when we deem it necessary.
We can provide at additional costs if specific analysis methods are required.
We are constantly trying to understand the reaction mechanisms and predict what byproducts may occur.
Data comparison with precursors is important.
It is also important for accurate and correct judgement to observe the solution mixture closely.

Purity of our compounds refers to the area ratio of the chromatogram, not the content nor the absolute purity.
We might possible to respond to your absolute purity measurement request, but it requires a considerable extra charge and time.
The amount of additional charge largely depends on both the target compound structure and the analysis method adopted.
There might several options for the analysis method, so please specify the method you would like to use.
If no specified method shown, qNMR will be used. It consumes a sample volume of 10mg or more, and the recovery may not be easy due to the added internal standard.

We usually do not guarantee the equivalent quality nor the same purity as the previous order. If you need this service, please tell us at the time of the first order. We might be able to meet your requirement with extra costs by stocking the first lot for comparative analysis.
Internal standard method might also be adopted.

All deuterium labelled products and some azide(N₃) containing compounds are exclusively for domestic market due to Japanese strict export regulations.
Deuterium compounds can be exported only in solutions of less than 200 ppm conc.
More precisely, content ratio of D(deuterium) to H(hydrogen) in the solution must be 5,000 times or more.
Please specify the solvent to be used for dilution.
