· JVASP-116418· CaAsO2

Calcium arsenite (CaAsO2) is an inorganic ceramic compound containing calcium, arsenic, and oxygen. This material is primarily encountered in specialized industrial contexts, particularly in legacy applications and arsenic-containing waste management systems, where it may form as a byproduct or stabilized phase. While not widely used in modern engineered products due to arsenic toxicity concerns, it remains relevant in environmental remediation, historical process metallurgy, and materials research focused on arsenic immobilization and ceramic stabilization of hazardous elements.

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.
