Disodium;dioxido(dioxo)chromium

Disodium;dioxido(dioxo)chromium is an inorganic chromium compound with the chemical formula CrNa2O4 and CAS number 7775-11-3. This substance has a molecular weight of 161.973 g/mol and appears as a yellow crystalline solid. It is classified as extremely hazardous due to its carcinogenic, mutagenic, and reproductive toxicity properties, requiring strict safety measures during handling and use in industrial applications.

Disodium;dioxido(dioxo)chromium is a yellow crystalline solid at room temperature with high water solubility. The compound has a molecular weight of 161.973 g/mol and contains hexavalent chromium in its structure. It is hygroscopic and can form hydrates when exposed to moisture. The substance is stable under normal conditions but decomposes at high temperatures, releasing toxic chromium compounds.

Disodium;dioxido(dioxo)chromium is primarily used in industrial applications including metal finishing, chrome plating, and as an oxidizing agent in chemical synthesis. It serves as a corrosion inhibitor in cooling systems and is utilized in the production of pigments and dyes. The compound also finds application in analytical chemistry and as a laboratory reagent, though its use is heavily restricted due to severe health hazards.

Disodium;dioxido(dioxo)chromium requires maximum protection during handling due to its extreme toxicity. Essential PPE includes chemical-resistant gloves, full-face respiratory protection, and complete body coverage. Work must be conducted in well-ventilated areas or under fume hoods. Avoid skin contact, inhalation, and ingestion completely. Use only in controlled industrial settings with trained personnel and emergency procedures in place.

Disodium;dioxido(dioxo)chromium must be stored in tightly sealed, corrosion-resistant containers in a cool, dry, well-ventilated area away from incompatible materials. Keep away from organic materials, reducing agents, and acids to prevent dangerous reactions. Storage areas should have restricted access, appropriate warning signs, and emergency equipment. Containers should be regularly inspected for integrity and properly labeled according to CLP regulations.

Immediate medical attention is critical for any contact with disodium;dioxido(dioxo)chromium. For skin contact, remove contaminated clothing and flush with copious amounts of water for at least 15 minutes. If inhaled, move to fresh air immediately and seek medical help. For eye contact, rinse thoroughly with water and get immediate medical attention. Never induce vomiting if ingested. Call poison control or emergency services immediately in all cases.

Disodium;dioxido(dioxo)chromium must be disposed of as hazardous waste through licensed waste management companies specializing in toxic metal compounds. The substance cannot be disposed of in regular waste streams due to its extreme toxicity and environmental persistence. Treatment typically involves stabilization and secure landfill disposal. All disposal activities must comply with local, national, and EU waste regulations including proper documentation and tracking procedures.

Disodium;dioxido(dioxo)chromium is classified under ADR as Class 6.1 (toxic substances), Packing Group II, indicating high toxicity requiring special transport precautions. Packages must be properly labeled with appropriate hazard markings and documentation. Transport requires trained personnel, emergency response information, and compliance with dangerous goods regulations. Vehicles must carry appropriate safety equipment and follow designated routes where applicable.

Disodium;dioxido(dioxo)chromium is subject to strict regulations under REACH and CLP due to its classification as carcinogenic, mutagenic, and toxic for reproduction (CMR Category 1B). The substance requires authorization for many uses and is restricted in consumer applications. Companies must comply with occupational exposure limits, worker protection requirements, and environmental discharge restrictions. Registration and safety data sheet obligations apply to all suppliers and users.

Disodium;dioxido(dioxo)chromium is available through specialized chemical distributors like OYSI, which serves the European market with technical-grade chemicals. Due to its hazardous classification, purchase is typically restricted to qualified industrial users with appropriate safety infrastructure and regulatory compliance. Buyers must demonstrate legitimate use, proper handling capabilities, and compliance with all applicable regulations before purchase authorization.
