Tricalcium diarsorate

Tricalcium diarsorate is an inorganic chemical compound with the molecular formula As2Ca3O8 and CAS number 7778-44-1. This arsenic-containing compound has a molecular weight of 398.07 g/mol and consists of calcium and arsenic in an oxidized form. It is classified as a toxic substance for transport purposes under ADR regulations, requiring careful handling and storage protocols in industrial applications.

Tricalcium diarsorate is a solid inorganic compound at room temperature, typically appearing as a crystalline powder. As an arsenic-containing calcium salt, it exhibits limited solubility in water and most common organic solvents. The compound is stable under normal storage conditions but should be protected from moisture and incompatible materials to maintain its integrity and prevent degradation.

Tricalcium diarsorate is primarily used in specialized industrial applications where arsenic compounds are required. Its specific applications include certain chemical synthesis processes, research purposes, and potentially in specialized materials manufacturing. Due to its toxic nature and regulatory restrictions, its use is limited to professional industrial settings with appropriate safety measures and qualified personnel.

Tricalcium diarsorate must be handled with extreme caution due to its toxic properties. Essential safety measures include wearing appropriate personal protective equipment such as chemical-resistant gloves, safety goggles, and respiratory protection. Work should be conducted in well-ventilated areas or under fume extraction systems. Personnel must be trained in proper handling procedures and emergency response protocols before working with this substance.

Tricalcium diarsorate should be stored in a cool, dry, well-ventilated area away from incompatible materials. The storage area must be secure and accessible only to authorized personnel due to the compound's toxic nature. Original containers should be kept tightly closed and properly labeled. Storage facilities should comply with local regulations for toxic substances and include appropriate spill containment measures.

Immediate action is required in case of contact with tricalcium diarsorate. For skin contact, remove contaminated clothing and wash the affected area thoroughly with soap and water. In case of eye contact, flush immediately with clean water for at least 15 minutes. If inhaled, move the person to fresh air immediately. Seek medical attention promptly in all cases of exposure, informing medical personnel about the specific substance involved.

Tricalcium diarsorate must be disposed of as hazardous waste according to local and national regulations. The substance cannot be disposed of with regular waste and requires specialized treatment through licensed hazardous waste disposal facilities. All containers, including empty ones, should be treated as hazardous waste. Consult local environmental authorities for specific disposal requirements and approved disposal facilities in your area.

Tricalcium diarsorate is classified under ADR Class 6.1 (Toxic substances), Packing Group II, indicating significant toxicity requiring special transport precautions. Transportation must comply with dangerous goods regulations, including proper packaging, labeling, and documentation. Only certified carriers experienced in handling toxic materials should transport this substance. Appropriate emergency response information must accompany all shipments.

Tricalcium diarsorate is subject to various chemical regulations due to its arsenic content and toxic properties. Under REACH regulation, it requires registration for commercial use in the EU. The substance must comply with CLP regulation for classification and labeling. It is not currently listed as a Substance of Very High Concern (SVHC), but local restrictions may apply depending on the jurisdiction and intended use.

Tricalcium diarsorate is available through specialized chemical distributors in Europe, including OYSI, which supplies industrial chemicals to European markets. Due to its toxic nature and regulatory requirements, purchases are typically restricted to qualified industrial users with appropriate handling capabilities. Buyers must provide proper documentation and comply with local regulations governing the acquisition and use of toxic substances.
