Sulfathiazole is an organosulfur compound used as a short-acting sulfa drug. Formerly, it was a common oral and topical antimicrobial, until less toxic alternatives were discovered.
Sulfathiazole exists in various forms (polymorphs). The imine tautomer is dominant, at least in the solid state. In this tautomer, the proton resides on the ring nitrogen.
