Tris(nickel(2+)) diarsorite

Tris(nickel(2+)) diarsorite is an inorganic compound with the molecular formula As2Ni3O6 and CAS number 74646-29-0. This substance contains both nickel and arsenic elements in its structure, with a molecular weight of 421.92 g/mol. It is classified as a Category 1A carcinogen and poses significant health and environmental risks, requiring careful handling and strict safety measures in industrial applications.

Tris(nickel(2+)) diarsorite is an inorganic solid compound with a molecular formula As2Ni3O6 and molecular weight of 421.92 g/mol. As a nickel-arsenic compound, it typically appears as a crystalline solid. Due to the presence of both nickel and arsenic in its structure, it exhibits properties characteristic of transition metal arsenates, though specific physical properties like color and solubility depend on the exact crystalline form.

Tris(nickel(2+)) diarsorite is primarily used in specialized industrial applications requiring specific nickel-arsenic compounds. Its applications may include use as a catalyst precursor, in metallurgical processes, or in specialized chemical synthesis. Given its high toxicity classification as a Category 1A carcinogen, its use is restricted to professional industrial settings with appropriate safety controls and regulatory compliance measures in place.

Tris(nickel(2+)) diarsorite requires extreme caution due to its Category 1A carcinogen classification and skin sensitization potential. Essential safety measures include wearing full protective equipment (respiratory protection, chemical-resistant gloves, protective clothing), working in well-ventilated areas or fume hoods, and avoiding skin contact and inhalation. Only trained personnel should handle this substance, following strict occupational safety protocols and regular health monitoring procedures.

Tris(nickel(2+)) diarsorite must be stored in a secure, dry, well-ventilated area away from incompatible materials and heat sources. Storage areas should be restricted to authorized personnel only, with appropriate warning signs and emergency procedures. The substance should be kept in original, tightly sealed containers to prevent contamination and exposure. Storage facilities must comply with local regulations for carcinogenic substances and environmental protection requirements.

Immediate action is required if contact occurs with tris(nickel(2+)) diarsorite. For skin contact, remove contaminated clothing and wash affected area thoroughly with soap and water for at least 15 minutes. If inhaled, move to fresh air immediately and seek medical attention. For eye contact, flush with clean water for 15 minutes. Given its carcinogenic nature, seek immediate medical advice in all exposure cases and inform healthcare providers of the substance involved.

Tris(nickel(2+)) diarsorite must be disposed of as hazardous waste through licensed waste management companies specializing in carcinogenic and heavy metal-containing materials. The substance cannot be disposed of in regular waste streams due to its toxicity and environmental hazard classification. Disposal must comply with national and EU waste regulations, including proper documentation and tracking. Empty containers should also be treated as hazardous waste requiring professional disposal.

Tris(nickel(2+)) diarsorite is classified under ADR Class 9 (Miscellaneous dangerous goods), Packing Group III for transportation purposes. It must be transported in appropriate UN-specification packaging with proper labeling including GHS pictograms (GHS07, GHS08, GHS09) and hazard information. Transport requires documentation including safety data sheets and emergency response information. Only certified carriers experienced in handling carcinogenic substances should transport this material.

Tris(nickel(2+)) diarsorite is subject to strict European regulations under REACH and CLP due to its carcinogenic classification. As a Category 1A carcinogen, it faces restrictions on use and requires authorization for certain applications. The substance must be registered under REACH, properly classified and labeled according to CLP regulation, and handled according to occupational safety directives. Additional national restrictions may apply for carcinogenic substances in workplace environments.

Tris(nickel(2+)) diarsorite is available through specialized chemical distributors like OYSI, which supplies technical chemicals across Europe. Due to its hazardous nature and regulatory requirements, purchase is restricted to qualified industrial users with appropriate safety facilities and regulatory compliance. Buyers must demonstrate legitimate industrial use, proper handling capabilities, and compliance with REACH registration requirements before procurement can be arranged through authorized European distributors.
