1,3-Dichloro-5,5-dimethylhydantoin (CAT: R032465) is a halogenated hydantoin derivative widely recognized for its potent oxidizing and antimicrobial properties. Featuring two chlorine atoms on the nitrogen atoms of a dimethylhydantoin ring, DCDMH serves as a stable source of active chlorine, making it ideal for disinfection, water treatment, and sanitation applications. It releases hypochlorous acid upon hydrolysis, effectively eliminating bacteria, fungi, and viruses. Its solid form ensures ease of handling, controlled release, and long shelf life. DCDMH is also used in organic synthesis as a chlorinating and oxidizing reagent, supporting diverse applications in industrial chemistry, public health, and environmental safety.
