4-Chlorothymol is mainly used as an antimicrobial and antiseptic agent in pharmaceuticals, oral care products, cosmetics, disinfectants, and laboratory applications.
4-Chlorothymol is widely known as 4-Chlorothymol or 2-isopropyl-5-methyl-4-chlorophenol, a chlorinated derivative of thymol.
4-Chlorothymol is a chlorinated derivative of thymol. While both belong to the phenolic compound family and show antimicrobial activities, chlorothymol contains an additional chlorine atom and it gives different chemical and functional characteristics.
4-Chlorothymol provides broad-spectrum antimicrobial activity against bacteria and fungi to help improve product preservation and hygiene while maintaining formulation stability.Â
