  • Applications

    SODIUM o-PHENYLPHENOL (CAS 1322-21-0) is commonly used as an organic synthesis intermediate, serving as a building block for dyes, pigments, and other specialty phenolic compounds. In polymer and plastics technology it can function as a stabilizer and processing aid to improve thermal and light stability. It is also employed as a processing additive in coatings, inks and adhesives to tune reactivity and performance. In industrial cleaning and surface-treatment formulations it can act as an active phenolic component aiding degreasing and residue control. Given the biocidal properties associated with related o-phenylphenol species, the sodium salt may be evaluated for antimicrobial or disinfectant use within applicable regulations and formulation limits.
