Pharmacology

Dichlorophen is a nontoxic laxative vermicide of chlorinated phenol compound. Dichlorophen is used as a veterinary fungicide, anthelmintic, and anti-protozoan, as well as an ingredient in antimicrobial soaps and shampoos. This agent probably acts by increasing the clearing of intestinal contents, thereby eradicating tapeworm infections from the intestines.

How it is made

By adding a CH2O yielding reagent, eg aqueous formaldehyde to p-chlorophenol.

Produced by reaction of 4-chlorophenol with 0.5 M aqueous formaldehyde solution with the addition of sulfuric acid at 50 - 65 °C.
