Disodium;selenate

Disodium selenate is an inorganic sodium salt of selenic acid with the chemical formula Na2O4Se and CAS number 13410-01-0. This compound has a molecular weight of 188.95 g/mol and serves as an important source of selenium in various industrial applications. It appears as a white crystalline solid that is highly soluble in water, making it useful for applications requiring bioavailable selenium compounds.

Disodium selenate appears as white crystalline solid at room temperature with high water solubility. The compound has a molecular weight of 188.95 g/mol and contains selenium in its highest oxidation state (+6). It is odorless and forms clear solutions when dissolved in water. The substance is stable under normal conditions but should be protected from moisture to prevent caking and maintain its crystalline structure.

Disodium selenate is primarily used as a selenium supplement in animal nutrition and feed formulations due to its high bioavailability. It serves as a raw material in the production of selenium-containing compounds and catalysts in chemical processes. The substance is also utilized in research applications, analytical chemistry, and as a selenium source in specialized industrial processes requiring precise selenium content.

Disodium selenate requires careful handling with appropriate personal protective equipment including gloves, safety glasses, and protective clothing. Work should be conducted in well-ventilated areas or under fume hoods to prevent inhalation of dust particles. Avoid generating dust during handling and use proper weighing techniques. Wash hands thoroughly after handling and avoid eating, drinking, or smoking in work areas where the substance is present.

Disodium selenate should be stored in tightly sealed containers in a cool, dry, well-ventilated area away from direct sunlight and heat sources. Keep containers closed when not in use to prevent moisture absorption and contamination. Store separately from incompatible materials such as strong acids and reducing agents. Ensure storage areas are equipped with appropriate spill containment measures and maintain proper inventory records.

Disodium selenate contact requires immediate action depending on the exposure route. For skin contact, wash thoroughly with soap and water for at least 15 minutes. If eye contact occurs, flush immediately with clean water for 15-20 minutes and seek medical attention. In case of inhalation, move to fresh air immediately. For ingestion, rinse mouth with water and seek immediate medical attention. Always consult medical professionals for proper evaluation.

Disodium selenate disposal must comply with local and national environmental regulations as it contains selenium, which is regulated in many jurisdictions. Contact licensed waste disposal companies specialized in hazardous chemical waste management. Do not dispose of in regular waste streams or pour down drains. Small laboratory quantities may require special collection procedures. Always consult local environmental authorities for specific disposal requirements in your region.

Disodium selenate is classified under ADR Class 6.1 (toxic substances) Packing Group I, indicating high toxicity requiring strict transport regulations. Proper UN-approved packaging and labeling are mandatory for shipment. Transport documents must include correct shipping names and hazard classifications. Only authorized carriers familiar with dangerous goods regulations should handle transportation. Ensure compliance with international transport regulations including IATA for air transport and IMDG for maritime shipping.

Disodium selenate is subject to various chemical regulations including REACH registration requirements in Europe for commercial use. The substance requires proper classification, labeling, and safety data sheet provision under CLP regulation. It is not currently listed as an SVHC (Substance of Very High Concern). Users must comply with occupational exposure limits and environmental discharge restrictions. Consult current regulatory databases for the most up-to-date requirements.
