Product Application of 2-Chlorophenol CAS#95-57-8

Parachlorophenol is mainly used in the pesticide, pharmaceutical, dye, plastic and other industries. It is also used as a denaturant for alcohol and a selective solvent for refined mineral oil. It can also be used for microscopic analysis and plant growth promoter. It is used to synthesize dyes. It reacts with dilute nitric acid to generate mono- and dinitro compounds, which are dye intermediates. It can further synthesize a variety of dyes, such as neutral brilliant green BL. It is used to make dyes and drugs, and is also used as a denaturant for alcohol and a selective solvent for refined mineral oil. In the pesticide industry, it is mainly used to synthesize triadimefon, cypermethrin, wool fungicide, anti-drop agent (multifunctional plant growth regulator), propanil (systemic insecticide), chlorfenapyr, insecticide, mite egg ester (non-systemic acaricide), miticide, and mitoxantrone; in the pharmaceutical industry, it is used for carboxylation to produce sodium 5-chloro-2-hydroxybenzoate, synthesize clofibrate, para-chlorophenoxyisobutyric acid and other drugs; it is also used to synthesize antioxidants such as BHA (butylated hydroxyanisole).
