Product sourcing, supplier sourcing chemicals dyes dyestuffs

We need to buy several dyes throughout the year. These dyes are rare, and are not readily available in the U.S.A.
Some of the dyes are stock dyes from Asia. Many of them need to be custom synthesized. Since the dyes are rare we do not have example synthesis for you.
In this project you will find sources of these dyes. We will provide you with CAS or structural drawing. We do not have C.I. numbers, or industry standard names. The dyes are primarily anthraquinone or azo dyes. We buy ACS grade dyes that have been purified by recrystallization, or other method, to remove salts and metal impurities.
Successful completion of this project may lead to additional F projects in the months to come.
