· JVASP-115426· NaAsO

Sodium arsenite (NaAsO₂) is an inorganic ceramic compound containing arsenic in oxidized form, typically encountered as a crystalline solid with limited structural applications due to its chemical composition. This material is primarily encountered in specialized industrial contexts such as wood preservation, pesticide formulations, and historical glass colorant applications rather than as a primary engineering structural material. The compound is notable primarily for its chemical functionality rather than mechanical performance, and its use in modern engineering is restricted due to toxicity concerns and regulatory limitations in most developed regions.

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.
