Overview

Dioxido(dioxo)chromium;bis(lead(2+));sulfate (CAS 1344-37-2) is a complex inorganic compound containing chromium, lead, and sulfate ions with significant toxicological properties. This compound, identified by EC number 215-693-7 and molecular formula CrO8Pb2S, represents a mixed metal oxide-sulfate system with a molecular weight of 630 g/mol. The substance combines chromium in its hexavalent oxidation state with divalent lead cations and sulfate anions, forming a complex crystalline structure. Due to the presence of both hexavalent chromium and lead compounds, this material exhibits severe health and environmental hazards, classified under multiple danger categories including carcinogenicity (Carc. 1B), reproductive toxicity (Repr. 1A), and aquatic toxicity. The compound's hazard profile necessitates extreme caution in handling, as indicated by the GHS08 (health hazard) and GHS09 (environmental hazard) pictograms and the signal word "Danger." The classification as STOT RE 2 highlights potential organ damage from repeated exposure, while its Aquatic Acute 1 and Aquatic Chronic 1 classifications reflect severe environmental impact potential. For transportation purposes, it falls under ADR Class 9 (miscellaneous dangerous goods). Industrial applications typically involve specialized processes where the unique properties of combined chromium-lead systems are required, such as certain pigment formulations and specialized ceramic applications. The compound shares structural similarities with related materials like dioxido(dioxo)chromium;dioxido(dioxo)molybdenum;tris(lead(2+));sulfate, which contains additional molybdenum components. OYSI provides this specialized compound to qualified industrial customers with appropriate handling capabilities and regulatory compliance frameworks.
