A photographic fixative used also in the manufacture of resins. According to the Fourth Annual Report on Carcinogens (NTP 85-002, 1985), this substance may reasonably be anticipated to be a carcinogen (Merck Index, 9th ed). Many of its derivatives are ANTITHYROID AGENTS and/or FREE RADICAL SCAVENGERS.
Phenylthiourea is a chemical compound with the formula C6H5NCS, used historically in scientific research as an inhibitor of tyrosinase activity, but now mostly replaced by other more specific agents, and infrequently used in certain diagnostic tests or as a reagent in organic synthesis.
A degradation product of ethylenebis(dithiocarbamate) fungicides. It has been found to be carcinogenic and to cause THYROID hyperplasia.
