Overview

5-chloro-2-(4-chlorophenoxy)phenol (CAS 3380-30-1) is a dichlorinated phenolic compound with antimicrobial and preservative properties. This specialized chemical compound belongs to the family of chlorinated phenols and exhibits significant biocidal activity due to its dual chlorine substitution pattern. The molecular structure features a phenoxy linkage between two chlorinated aromatic rings, resulting in enhanced stability and antimicrobial efficacy compared to simpler phenolic compounds. With a molecular weight of 255.09 g/mol and formula C12H8Cl2O2, this substance demonstrates the characteristic properties of halogenated organic compounds used in industrial preservation applications. The compound presents important safety considerations, classified as causing serious eye damage (Eye Dam. 1) and posing significant environmental hazards to aquatic life both acutely and chronically (Aquatic Acute 1, Aquatic Chronic 1). The GHS pictograms GHS05 and GHS09 indicate corrosive properties and environmental dangers respectively, requiring careful handling protocols and appropriate personal protective equipment during industrial use. Primary industrial applications include use as a preservative in metalworking fluids, antimicrobial agent in industrial coatings, and biocide in water treatment systems where its dual-chlorine structure provides enhanced antimicrobial spectrum. While structurally different from compounds like 4-(4-hydroxy-3-methylphenyl)sulfanyl-2-methylphenol, both serve important roles in industrial preservation chemistry, though through different mechanisms of action. Transportation falls under ADR Class 9 (miscellaneous dangerous goods), reflecting its specific handling requirements for logistics and storage. OYSI maintains reliable supply chains for this technical chemical, supporting European industrial clients with consistent availability and regulatory compliance.
