Bromoethene

Bromoethene is an organobromine compound with the chemical formula C2H3Br and CAS number 593-60-2. It is a halogenated alkene featuring a vinyl group bonded to a bromine atom, with a molecular weight of 106.95 g/mol. This compound exists as a flammable gas under normal conditions and is classified as a Category 1B carcinogen, requiring careful handling in industrial applications.

Bromoethene is a colorless gas at room temperature and atmospheric pressure, characteristic of its classification as a pressurized gas. As an unsaturated organohalogen compound, it exhibits moderate polarity due to the bromine substituent. The compound has limited water solubility but dissolves readily in organic solvents. Its vinyl structure makes it reactive toward polymerization and addition reactions.

Bromoethene serves primarily as a chemical intermediate in organic synthesis and polymer chemistry. It is used in the production of specialty polymers, flame retardants, and as a building block for more complex organobromine compounds. The compound finds applications in pharmaceutical synthesis, agrochemical manufacturing, and as a monomer in specialized polymerization reactions where bromine functionality is required.

Bromoethene requires extensive safety precautions due to its flammable and carcinogenic properties. Personnel must wear appropriate respiratory protection, chemical-resistant gloves, and protective clothing. Work should be conducted in well-ventilated areas or under fume hoods, with strict elimination of ignition sources. Gas detection systems and emergency procedures must be in place due to its pressurized gas nature and health hazards.

Bromoethene must be stored in specialized pressure vessels designed for flammable gases, away from heat sources, sparks, and incompatible materials. Storage areas should be cool, well-ventilated, and equipped with appropriate safety systems. The compound should be kept separate from oxidizing agents, strong bases, and materials that could initiate polymerization. Regular inspection of containers and safety equipment is essential.

Immediate evacuation from the exposure area to fresh air is crucial in case of bromoethene contact or inhalation. For skin contact, remove contaminated clothing and wash thoroughly with soap and water. In case of eye contact, flush immediately with plenty of clean water for at least 15 minutes. Seek immediate medical attention in all exposure cases, informing healthcare providers of the carcinogenic nature of the substance.

Bromoethene disposal must comply with local and international hazardous waste regulations due to its carcinogenic classification. The compound cannot be released to the atmosphere or disposed of in regular waste streams. Professional hazardous waste disposal services should handle destruction through appropriate high-temperature incineration or other approved methods. Documentation and manifests are required for proper waste tracking and regulatory compliance.

Bromoethene is classified under ADR Class 2 as a dangerous good, requiring specialized transport procedures for pressurized gases. Transportation must use approved pressure containers and vehicles equipped for hazardous gas transport. Proper labeling with GHS02, GHS04, and GHS08 pictograms is mandatory, along with appropriate shipping documentation. Drivers require hazardous materials training and certification.

Bromoethene is subject to comprehensive chemical regulations including REACH registration requirements in Europe and CLP classification as a Category 1B carcinogen. Its flammable gas classification triggers additional workplace safety regulations and emission controls. Users must implement appropriate risk management measures and may require special permits or notifications depending on quantities handled and local jurisdiction requirements.

Bromoethene is available through OYSI, a European distributor of specialty chemicals serving industrial customers across the continent. As a regulated carcinogenic substance, purchase requires proper documentation, safety protocols, and compliance with local regulations. OYSI provides technical support and regulatory guidance to ensure proper handling and use of this specialized chemical intermediate by qualified industrial users.
