Overview

Hydrogen arsorate;lead(2+) (CAS 7784-40-9) is an inorganic lead-arsenic compound with highly toxic and carcinogenic properties. This chemical substance, also identified by EC number 232-064-2, represents a complex inorganic compound containing both lead and arsenic elements with the molecular formula AsHO4Pb and a molecular weight of 347 g/mol. The compound falls under multiple severe hazard classifications, including Category 1A carcinogen and reproductive toxicant, making it one of the most hazardous materials in industrial chemistry. Its classification as Acute Tox. 3 and STOT RE 2 under GHS regulations reflects its immediate and long-term health risks, while its aquatic toxicity ratings emphasize significant environmental concerns. The substance requires extreme caution in handling due to its dual toxicity from both lead and arsenic components. Unlike simpler toxic compounds such as dichlorocadmium, hydrogen arsorate;lead(2+) presents combined heavy metal toxicity mechanisms. The GHS08, GHS06, and GHS09 pictograms indicate health hazards, acute toxicity, and environmental dangers respectively, with "Danger" as the signal word. Transportation falls under ADR Class 6.1, designating it as a toxic substance requiring specialized logistics protocols. Industrial applications are highly restricted due to its extreme toxicity profile, typically limited to very specific research applications under controlled laboratory conditions. In contrast to other toxic compounds like N-methylaniline, which finds broader industrial use, hydrogen arsorate;lead(2+) applications remain extremely specialized due to regulatory restrictions and health considerations. OYSI maintains availability of this specialized compound for qualified industrial and research customers with appropriate safety certifications and handling capabilities.
