Thiophanate-methyl is an organic compound with the formula C6H4(NHC(S)NH(CO)OCH3)2. The compound is a colorless or white solid, although commercial samples are generally tan-colored. It is prepared from o-phenylenediamine. It is a widely used fungicide used on tree, vine, and root crops.[1]

Methods for its analysis have received considerable attention.[2][3][4] It is commonly used to treat botrytis bunch rot and gray mold caused by Botrytis cinerea strawberry in California.[5] Thiophanate-methyl acts as a fungicide via its primary metabolite carbendazim.
