The main purpose:

P-Chlorophenol is mainly used in pesticides, medicine, dyes, plastics 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 microscope analysis and plant growth promoter.

It is used to synthesize dyes, reacting with dilute nitric acid to generate mono- and dinitro compounds are dye intermediates; it can further synthesize a variety of dyes, such as neutral brilliant green BL. In the pesticide industry, it is mainly used to synthesize Fenpyrin, Mimidone, Fleece Fungicide, Antifox (Multifunctional Plant Growth Regulator), Profenofos (Systemic Pesticide), Tetraphos, Insecticide, Difenophos (non-systemic acaricide), dicofenate, dicofen; used in the pharmaceutical industry to carboxylate sodium 5-chloro-2-hydroxybenzoate, synthesize antomin and p-chlorophenoxy isobutyl Acid and other drugs; it is also used to synthesize antioxidant BHA (butylated hydroxyanisole) and so on.

Packaging, storage and transportation

P-Chlorophenol is packaged in an iron drum lined with plastic film or kraft paper, and placed in a dry, ventilated and cool place. Keep away from fire sources, and avoid mixed shipment with iron salts, heavy metal salts, potassium permanganate, hydrogen peroxide, iodine, bromine, protein, collodion, etc.
