Dichlorophen

Dichlorophen (CAS 97-23-4) is a chlorinated bisphenol compound also known under the trade names Antiphen, Anthiphen, and Dicestal. It carries no assigned E-code and is classified under HS code 29081990 within the pharmaceutical intermediates category.

In water treatment, dichlorophen functions as a biocide by disrupting microbial cell membranes, controlling algae and bacteria in industrial cooling systems and process water. In personal care formulations, it acts as a preservative against gram-positive bacteria and fungi, and has historically been applied in agricultural contexts as an anthelmintic intermediate targeting parasitic organisms.

Dichlorophen is supplied as a white to off-white powder meeting REACH registration requirements for European commerce. Buyers should confirm applicable national or sector-specific restrictions prior to procurement, as regulatory status varies by application and jurisdiction. Standard packaging formats and custom quantities are available on request.
