Schem's advantages

• Our manufacturing techniques have evolved over 35 years of custom synthesis of organic compounds.
• For known compounds for which synthetic methods are available in the literature, we have successfully synthesized almost 100% of the compounds.
• We have extensive experience in the synthesis of new compounds and are willing to work on compounds for which synthetic methods are unknown.
  Let us synthesise new or challenging compounds that have been abandoned elsewhere.

Using our original expertise and techniques, we have synthesised and isolated over 50,000 organic chemicals.

Special compounds shown on our website are selected from our synthesis over the last few decades which do not conflict with our customers' confidentiality agreements.

Most of these chemicals are highly specialised and only available from us.

You can use the "Compound Search" window at the bottom of this page to enter the product number and get information on your compounds.

CAS RN, molecular formula, compound name can be used as keywords.

We specialise in the custom synthesis of rare organic compounds for laboratory and almost any organic compounds upto several hundred milligrams scale can be handled. We can handle organic compounds of any structure not on the list,
