3',4'-Dichlorosalicylanilide is a versatile antimicrobial agent used as both an antifungal and antibacterial compound. In pharmaceutical and personal care applications, it effectively treats skin infections, prevents fungal and bacterial growth, and is incorporated into medicated creams, ointments, powders, soaps, and lotions for topical use to maintain hygiene. It is also employed in veterinary medicine to manage similar infections in animals. Industrially, it acts as a biocide in products such as paints, wood coatings, construction materials, and textiles, extending their lifespan by protecting against microbial damage and preventing mold or odors, particularly in humid environments.
