PAKISTAN INDIA dye chemical sourcing

Project to survey dyes in Pakistan and India, etc. We need to buy several dyes throughout the year. These dyes are rare, and are not readily available in the U.S.A. A few of the dyes are probably stock dyes in Pakistan and India. 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. You can also sell us these dyes if you like. In general we buy anthraquinone or azo dyes. We buy ACS grade dyes that have been purified by recrystallization, or other method, to remove salts and metal impurities. You are a chemistry graduate working on your masters or phd or you are a 4th year chemistry undergraduate or have background in dyestuffs. Thank you for reading this project.
