Widely used as an intermediate in the synthesis of triclosan (5-chloro-2-(2,4-dichlorophenoxy)phenol), a broad-spectrum antimicrobial agent. Triclosan is incorporated into personal care products, cosmetics, soaps, toothpastes, and medical devices to inhibit the growth of bacteria and fungi. The compound's diphenyl ether structure with chloro and hydroxyl groups facilitates further halogenation and modifications for biocide production. It is also employed in research for developing novel antimicrobials and as a component in the synthesis of heat- and chemical-resistant polymers for plastics and fibers.
