  • Applications

    Phenylmercuric nitrate (CAS 55-68-5) is used as a preservative/antimicrobial agent and antiseptic in certain cosmetics and pharmaceutical formulations, particularly in skin-care products and ophthalmic solutions, with strict regulatory controls. It has also been employed as a biocide in industrial coatings and printing inks to prevent microbial growth during storage and use. In addition, it may serve as a preservative and antimicrobial component in cleaning formulations and may act as an intermediate in some industrial manufacturing processes, subject to regulatory restrictions and formulation limits.
