Tribromoarsane

Tribromoarsane is an inorganic arsenic compound with the chemical formula AsBr3 and CAS number 7784-33-0. This substance has a molecular weight of 314.63 g/mol and belongs to the family of arsenic halides. Tribromoarsane is formed by the combination of arsenic with three bromine atoms, creating a covalent compound that exhibits typical properties of arsenic-bromine complexes used in specialized chemical applications.

Tribromoarsane appears as a crystalline solid at room temperature with a characteristic yellowish to orange color. The compound is sensitive to moisture and can decompose in the presence of water, releasing hydrogen bromide vapors. It has limited solubility in polar solvents but dissolves readily in organic solvents such as carbon disulfide and benzene. The compound exhibits a pungent, irritating odor typical of bromine-containing substances.

Tribromoarsane serves primarily as a chemical intermediate in organic synthesis and semiconductor manufacturing processes. It is utilized in the production of organoarsenic compounds and as a brominating agent in specialized chemical reactions. The compound finds applications in research laboratories for analytical chemistry purposes and in the electronics industry for the preparation of high-purity arsenic compounds used in semiconductor doping processes.

Tribromoarsane requires careful handling with appropriate personal protective equipment including chemical-resistant gloves, safety goggles, and respiratory protection. Work should be conducted in a well-ventilated area or under a fume hood to prevent inhalation exposure. Avoid contact with skin, eyes, and clothing, as the compound can cause irritation and potential health hazards. Always use proper laboratory techniques and ensure emergency shower and eyewash stations are readily accessible.

Tribromoarsane should be stored in a cool, dry, well-ventilated area away from moisture and incompatible materials. Keep containers tightly sealed and protected from light and heat sources. The compound should be stored separately from strong oxidizing agents, alkalis, and water-reactive substances. Use appropriate secondary containment and ensure storage areas are equipped with adequate ventilation systems to prevent vapor accumulation.

Immediate action is required upon contact with tribromoarsane. For skin contact, remove contaminated clothing and flush the affected area with copious amounts of water for at least 15 minutes. In case of eye contact, rinse immediately with clean water for at least 15 minutes while holding eyelids open. If inhaled, move the person to fresh air immediately. Seek immediate medical attention in all cases and provide safety data sheet information to medical personnel.

Tribromoarsane disposal must comply with local, national, and international hazardous waste regulations due to its arsenic content. The compound should never be disposed of in regular waste streams or sewage systems. Contact licensed hazardous waste disposal companies for proper treatment and disposal. Small laboratory quantities may require neutralization or chemical treatment before disposal, following institutional waste management protocols and regulatory guidelines.

Tribromoarsane is classified under ADR regulations as Class 6.1 (toxic substances) with Packing Group II, indicating moderate toxicity levels. Transportation requires appropriate UN-specification packaging and proper hazardous material documentation. Vehicles must display appropriate hazard placards and drivers need hazardous materials training certification. Shipments should include emergency response information and comply with international dangerous goods transportation regulations for road, rail, and air transport.

Tribromoarsane falls under various chemical regulations including REACH registration requirements in Europe due to its commercial use. The compound is subject to workplace safety regulations and occupational exposure limits due to its arsenic content. It is not currently listed as a Substance of Very High Concern (SVHC) under REACH, but users must comply with CLP classification and labeling requirements and maintain appropriate safety documentation.
