2-Chloro-5-methylphenol is organic compound used in the synthesis of troarylpyrazoles as anti-cancer agents. 2-Chloro-5-Methylphenol is extensively used in the manufacture of resins, herbicides, pharmaceuticals, tricresylic acid surfactants. Wastewater from these industries together with coal-conversion unit and petrochemicals contain high concentration of cresol. Discharge of cresols into the environment poses significant health threat due to carcinogenic and refractory nature.
