· Hg(AsO3)2

Mercury arsenite, Hg(AsO₃)₂, is an inorganic ceramic compound formed from mercury and arsenite ions. This material belongs to the family of heavy-metal arsenite salts and is primarily of academic and historical interest rather than modern industrial use. Its toxicity and environmental hazards make it unsuitable for most contemporary engineering applications, though it may appear in legacy formulations, historical pigments, or specialized analytical contexts.

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.
