Description and Uses

2-Chlorotoluene can be mineralized completely by Rhodococcus, strain OCT 10 DSM 45596(T). It is used in the preparation of 3-chloro-4-methylcatechol and 4-chloro-3-methylcatechol. The oxidation of 2-chlorotoluene is very well catalyzed by the enzymes: toluene dioxygenase of P. putida F1 and chlorobenzene dioxygenase from Burkholderia, strain PS12.

Solvent; synthesis of dyes, pharmaceuticals, and synthetic rubber compounds
