Description

Dichlorophen (CAS 97-23-4 ) is a chlorinated bisphenol compound used industrially as a broad-spectrum biocide and preservative. It controls microbial and fungal growth across personal care, agricultural, and water treatment applications. In personal care formulations, it functions as a preservative in shampoos, creams, and topical products where fungal and bacterial contamination must be controlled. Reliable antimicrobial performance is a key requirement. Agricultural products utilize it as an active ingredient in antifungal treatments for crops and as a component in veterinary antiparasitic preparations. It is highly effective in these specialized environments. Water treatment operations incorporate it to suppress algae and microbial biofilm formation in industrial water systems and cooling towers. This ensures the efficiency and safety of large-scale industrial cooling processes. It also serves as a pharmaceutical intermediate in the synthesis of antiparasitic active substances, supporting API manufacturing pipelines. This versatility makes it a valuable chemical for various synthesis routes. The product is supplied as a white to off-white crystalline powder. Standard grades include technical and pharmaceutical-grade material, with specifications aligned to USP and BP requirements. Quality standards may also align with Ph.Eur. , EP , or FCC depending on the regulated end uses. Packaging typically ranges from kilogram-scale laboratory quantities to bulk industrial orders. The material is handled according to strict safety protocols depending on the intended application and regulatory context. This ensures consistent quality for all industrial and pharmaceutical customers. Contact us for supply of Dichlorophen Request Quote
