Molecular bromine

Molecular bromine is a highly reactive halogen element existing as a diatomic molecule (Br2) with CAS number 7726-95-6. This chemical compound has a molecular weight of 159.81 g/mol and appears as a dark reddish-brown liquid at room temperature. It is classified as a corrosive substance with acute toxicity properties, making it essential for various industrial applications while requiring careful handling due to its hazardous nature.

Molecular bromine is a dense, dark reddish-brown liquid at room temperature with a characteristic sharp, penetrating odor. It readily evaporates to form toxic orange-red vapors and has high density compared to water. The substance is moderately soluble in water, forming hydrobromic and hypobromous acids, and highly soluble in organic solvents. Its corrosive nature and volatility make it reactive with most organic materials and metals.

Molecular bromine serves as a key intermediate in pharmaceutical synthesis, flame retardant production, and agricultural chemical manufacturing. It is widely used in the production of brominated compounds for various industrial applications, including water treatment as a disinfectant and sanitizer. Additionally, it finds application in analytical chemistry as a reagent for organic synthesis and in the manufacturing of photographic chemicals and drilling fluids.

Molecular bromine requires strict safety protocols including full personal protective equipment: chemical-resistant gloves, eye protection, and respiratory protection in well-ventilated areas. Work should be conducted in fume hoods due to toxic vapor emission. Avoid contact with skin, eyes, and clothing as it causes severe chemical burns. Emergency eyewash and shower facilities must be readily accessible, and personnel should be trained in proper handling procedures before use.

Molecular bromine must be stored in tightly sealed, corrosion-resistant containers in cool, dry, well-ventilated areas away from direct sunlight and heat sources. Keep separate from organic materials, metals, and reducing agents due to incompatibility risks. Storage areas should have appropriate containment systems and be equipped with emergency spill control measures. Regular container inspection is essential due to the corrosive nature of bromine vapors.

Immediate action is critical for molecular bromine exposure. For skin contact, remove contaminated clothing and flush affected area with copious amounts of water for at least 15 minutes. In case of eye contact, rinse immediately with water and seek medical attention. If inhaled, move to fresh air immediately and seek medical care. For ingestion, do not induce vomiting and seek immediate medical attention. Always consult emergency services for serious exposures.

Molecular bromine disposal must comply with local and European waste regulations as hazardous chemical waste. It cannot be disposed of through regular waste streams due to its corrosive and toxic properties. Contact licensed hazardous waste disposal companies for proper treatment and neutralization. Small quantities may be neutralized under controlled conditions by qualified personnel using appropriate reducing agents, but professional disposal is recommended for safety and regulatory compliance.

Molecular bromine is classified as ADR Class 8 (corrosive substances), Packing Group I, indicating high danger level during transport. It requires specialized corrosion-resistant packaging and appropriate hazard labeling including GHS pictograms GHS06, GHS05, and GHS09. Transportation must follow strict ADR regulations with proper documentation, trained personnel, and emergency response procedures. Only authorized carriers with appropriate equipment and certification should handle bromine shipments.

Molecular bromine is subject to comprehensive European chemical regulations including REACH registration and CLP classification requirements. It carries the signal word 'Danger' and is classified as Acute Tox. 2, Skin Corr. 1A, and Aquatic Acute 1 under CLP regulation. While not currently listed as SVHC, it requires proper safety data sheets, risk assessments, and compliance with occupational exposure limits. Industrial users must implement appropriate risk management measures.

Molecular bromine is available through OYSI, a specialized European distributor of industrial chemicals. As a professional chemical supplier, OYSI provides molecular bromine with proper documentation, safety data sheets, and regulatory compliance for industrial customers. Given the hazardous nature and regulatory requirements of bromine, purchasing from established distributors like OYSI ensures proper handling, packaging, and legal compliance throughout the supply chain for European markets.
