It binds to the sterol biosynthesis pathway and disrupts the production of ergosterol, which is an essential component for fungal cell membranes. Trimethylsulfoxonium bromide is an intermediate compound that can be used as a bactericidal thiazole derivative. It can be used in the production of methylcobalamin and in the preparation of novel metconazoles.
