Hello Guys,

I need help to search for thymohydroquinone standard with the cas no. 2217-60-9. Can you guys give me some suggestions? I have tried Accustandard, Dr. Ehrenstoffer, Chromadex, Sigma. But none of them supplying the above chemical. Pls help. Thanks a million.

Note sure if this is the quality you want, but try "Honest Joy Chemicals"

With a company name like that how can you go wrong?, but there were several others that a Google seach on the CAS Number revealed.

Please keep having fun,
