Molecular bromine

Molecular bromine is a diatomic halogen element with the chemical formula Br2 and CAS number 7726-95-6. It exists as a reddish-brown liquid at room temperature with a strong, pungent odor. With a molecular weight of 159.81 g/mol, bromine is highly reactive and corrosive. It is classified as acutely toxic, skin corrosive, and harmful to aquatic life, requiring careful handling in industrial applications.

Molecular bromine is a dense, reddish-brown liquid at room temperature with a characteristic sharp, irritating odor. It readily vaporizes to form orange-brown fumes and is moderately soluble in water, forming hydrobromic and hypobromous acids. Bromine has a boiling point of 58.8°C and freezing point of -7.2°C. It is highly reactive with organic compounds and metals, making it corrosive to most materials.

Molecular bromine is primarily used in the production of flame retardants, pharmaceuticals, and agrochemicals. It serves as an intermediate in manufacturing organobromine compounds and is utilized in water treatment applications as a disinfectant. The chemical industry employs bromine in the synthesis of dyes, photographic chemicals, and drilling fluids. It also finds applications in analytical chemistry and as a catalyst in certain organic reactions.

Molecular bromine requires strict safety measures due to its corrosive and toxic nature. Always wear chemical-resistant gloves, protective clothing, eye protection, and respiratory equipment when handling. Work in well-ventilated areas or under fume hoods to avoid vapor inhalation. Use appropriate tools and containers made of compatible materials. Emergency eyewash stations and safety showers should be readily accessible. Never handle bromine without proper training and safety protocols.

Molecular bromine must be stored in tightly sealed, corrosion-resistant containers in a cool, dry, well-ventilated area away from direct sunlight. Keep away from incompatible materials such as metals, organic compounds, and reducing agents. Storage areas should be equipped with appropriate containment systems and fire suppression equipment. Maintain temperatures below 25°C and ensure containers are properly labeled with hazard information.

Immediate action is crucial in case of bromine contact. For skin contact, remove contaminated clothing and flush affected area with copious amounts of water for at least 15 minutes. If inhaled, move person to fresh air immediately and seek medical attention. For eye contact, rinse thoroughly with water for at least 15 minutes. Never induce vomiting if ingested. Seek immediate medical attention in all cases of exposure.

Molecular bromine disposal must comply with local and international hazardous waste regulations. Never discharge bromine into drains, soil, or waterways due to its environmental toxicity. Contact licensed hazardous waste disposal companies for proper treatment and disposal. Small quantities can be neutralized by qualified personnel using appropriate reducing agents under controlled conditions. Always consult local environmental authorities for specific disposal requirements and regulations.

Molecular bromine is classified as ADR Class 8 (Corrosive substances), Packing Group I, indicating high danger level. Transportation requires UN-approved packaging designed for corrosive liquids and proper hazard labeling with corrosive pictograms. Vehicles must carry appropriate emergency equipment and documentation. Only trained personnel should handle bromine shipments, and transport must comply with international dangerous goods regulations including ADR for road transport in Europe.

Molecular bromine is subject to comprehensive chemical regulations including REACH registration in Europe and CLP classification requirements. It carries the signal word 'Danger' with pictograms GHS06, GHS05, and GHS09, indicating acute toxicity, corrosivity, and environmental hazards. While not listed as a SVHC substance, it requires safety data sheets, proper labeling, and compliance with occupational exposure limits. Transportation regulations also apply due to its corrosive classification.

Molecular bromine is available through specialized chemical distributors in Europe, including OYSI, which supplies industrial-grade bromine to professional users across European markets. Purchase requires proper documentation due to regulatory requirements and safety considerations. Buyers typically need to demonstrate legitimate industrial use and appropriate handling capabilities.
