  • Applications

    Mercuric chloride (Chemical name: Mercuric Chloride; CAS number: 7487-94-7) is used as a reagent and intermediate in inorganic synthesis, providing Hg2+ for qualitative tests and for the preparation of various organomercury compounds; it has historically served as a mordant in textile dyeing to fix colors, and as a fixative in histology and biological specimen preservation; it has been employed as a topical antiseptic and disinfectant in laboratory and medical settings, albeit with stringent controls today due to toxicity; it has been used as a heat stabilizer for PVC and related polymers, and in analytical chemistry it serves as a reagent for certain chloride tests and other standard procedures.
