 4-Chlorophenyl-4-chlorobenzene sulfonate (CAS NO.80-33-1) have a higher activity to many mites and eggs which eat plants. There are significant residual activity of killing the eggs and slight insecticidal activity. 4-Chlorophenyl-4-chlorobenzene sulfonate (CAS NO.80-33-1) is used for all kinds of mites of cotton and fruit trees. It is generally no phytotoxicity. Also it can be used as anti-moth wool textile agent.

To 4-Chlorobenzenesulfonic acid and Chlorosulfonic acid as raw materials, through the following steps to produce the kill mites ester. The content of industrial products of kill mites ester is over 95%, when the consumption of raw materials fixed: The 4-Chlorobenzenesulfonic acid (92%) 1230kg / t, Chlorosulfonic acid (95%) 2100kg / t, Phenol (98%) 310kg / t, Sodium hydroxide (95%) 157kg / t, Chlorine ( 99.5%) 250kg / t, Ferric chloride (99%) 1.8kg / t.

Moderately toxic by ingestion and possibly other routes. Questionable carcinogen with experimental tumorigenic data. A pesticide. When heated to decomposition it emits very toxic fumes of Cl⁻ and SO_x. See also SULFONATES and CHLORINATED HYDROCARBONS, AROMATIC.

 4-Chlorophenyl-4-chlorobenzene sulfonate (CAS NO.80-33-1) is also called Ovotox(r) ; Ovex ; p-Chlorophenyl-p-chlorobenzene sulfonate ; Orthotran(r) ; Mitran(r) ; (4-Chloor-fenyl)-4-chloor-benzeen-sulfonaat . 4-Chlorophenyl-4-chlorobenzene sulfonate (CAS NO.80-33-1) is chemical stability.  But it decomposits when encountered alkali. 4-Chlorophenyl-4-chlorobenzene sulfonate (CAS NO.80-33-1) is moderate toxic.It will produce toxic chloride and sulfur oxide gases when buring. So the storage environment should be ventilate, low-temperature and dry.Keep it separate from raw materials of food.
