· HgCl2

Mercury(II) chloride (HgCl2) is an inorganic salt compound classified as a ceramic material, consisting of mercury and chlorine in a 1:2 stoichiometric ratio. Historically used in pharmaceutical and laboratory applications, HgCl2 has been employed in disinfectants, fungicides, and analytical chemistry due to its antimicrobial properties, though its use has declined significantly in modern practice due to mercury toxicity concerns and regulatory restrictions. Contemporary engineering interest is primarily academic and materials-research focused, exploring its solid-state properties and crystal structure rather than new industrial applications.

Regulatory Screening

Environmental

RoHS, REACH, and Prop 65 statuses are validated against official substance lists (ECHA SVHC Candidate List, OEHHA Prop 65, RoHS Annex II). Other regulations are estimated from composition and material classification. All screening is a starting point for due diligence — always verify with your supplier before making compliance decisions.
