4-Chloro-2-isopropyl-5-methylphenol

4-Chloro-2-isopropyl-5-methylphenol is a white crystals or powder. M.P. 62℃. Almost insoluble in water, soluble in alcohol and oils. Thymol-like odor, but not as sweet, more "medicinal", less condiment-like. However, the taste is definitely sweeter than that of Thymol. A 0.1% solution in water (saturated) has an odor very closely resembling that of Thymol.

4-Chloro-2-isopropyl-5-methylphenol finds more extensive use as a bactericidal additive than as a perfume chemical. It is included in this work because it occasionally appears in products related to the perfumer's or flavorist's work, and may interfere with his efforts to perfume or flavor the prod uct.

4-Chloro-2-isopropyl-5-methylphenol is preservative; which is used in preparation method of nano-resin multifunctional ceramic tile interface agent.

4-Chloro-2-isopropyl-5-methylphenol is prepared by reaction of equimolar amounts of propene and 4-chloro-3-methylphenol in the presence of bleaching clay under pressure at 140–160 ℃ or by chlorination of thymol with SO2Cl2 in chloroform. On account of its microbicidal properties, chlorothymol is of importance as a raw material for disinfectants.

Photocatalytic degradation of 4-chloro-2-isopropyl-5-methylphenol has been investigated in water and in simulated soil washing wastes containing Brij 35 in the presence of TiO₂ dispersions.
