Phenyl Mercuric Acetate is an organomercury compound with the chemical formula CH₃CO₂HgC₆H₅. It belongs to the arylmercury class and consists of a phenyl group bonded to mercury attached with an acetate group. The compound generally appears as colorless, lustrous crystalline prisms. It is sparingly soluble in water but dissolves in ethanol, benzene, and acetic acid. It is a member of the broader class of organic mercury compounds and exhibits characteristic chemical reactivity associated with its arylmercury structure.
