4-Chloro-2-methylphenol Chemical Properties,Usage,Production
Chemical Properties
Off-white to slightly brownish crystalline solid
Uses
4-Chloro-2-methylphenol is a transformation/degredation product of herbicides found in the environment through landfills and runoff.
Definition
ChEBI: 4-chloro-2-methylphenol is a member of the class of phenols that is o-cresol in which the hydrogen para to the hydroxy group is replaced by a chlorine. It is a member of phenols and a member of monochlorobenzenes. It is functionally related to an o-cresol.
Application
4-Chloro-2-methylphenol is an important pharmaceutical intermediate ingredient used in the manufacture of herbicides (Mecoprop, MCPA, and MCPB), as an additive tracer for resist plasma etching. It is used as a closed system intermediate in the production of phenoxy herbicides. It is also used as a disinfectant or bactericide.

General Description
Dark red flakes with waxy texture. Insoluble in water.
Air & Water Reactions
Insoluble in water.
Reactivity Profile
4-Chloro-2-methylphenol can react vigorously with concentrated sodium hydroxide solutions. Also reacts with other bases, acid chlorides, acid anhydrides, and oxidizing agents. Corrodes steel, brass, copper and copper alloys [NTP, 1992)]. A large quantity left in contact with concentrated sodium hydroxide solution for 3 days reacted violently, attaining red heat and evolving fumes that ignited explosively. The heat of reaction dissipated poorly because of the high viscosity of the mixture [Quart. Safety Summ., 1957, 28, 39].
Fire Hazard
4-Chloro-2-methylphenol is probably combustible.
Flammability and Explosibility
Non flammable
Purification Methods
Purify the phenol by crystallisation from pet ether (m 51o) and by zone melting. [Beilstein 6 H 359, 6 I 174, 6 II 332, 6 III 1264, 6 IV 1987.]
