CAS 88-04-0 4-Chloro-3.5-dimethylphenol
Overview
4-Chloro-3.5-dimethylphenol (Chloroxylenol, PCMX; CAS 88-04-0; C₈H₉ClO) is a high-assay, white to off-white crystalline phenolic antimicrobial raw material used to manufacture hand soaps/surgical scrubs, personal-care cleansers, household & HI&I disinfectants, and preservative systems.
Product Description
88-04-0 4-Chloro-3,5-dimethylphenol
Produced under controlled conditions to deliver low moisture and low phenolic impurities, PCMX offers broad-spectrum activity (Gram-positive coverage with selected Gram-negatives and fungi) and helps prevent odor, color shift, and microbial growth in surfactant bases and hard-surface cleaners.
