Bromoethane

Bromoethane is an organohalogen compound with the molecular formula C2H5Br and CAS number 74-96-4. This chemical substance has a molecular weight of 108.97 g/mol and belongs to the alkyl halide family. It is classified as a flammable liquid with carcinogenic properties and acute toxicity potential. Bromoethane is commonly used as an intermediate in organic synthesis and industrial applications requiring halogenated compounds.

Bromoethane is a colorless liquid at room temperature with a characteristic sweet, ether-like odor. It has a boiling point of approximately 38.4°C and is denser than water. The compound is moderately soluble in water but highly soluble in organic solvents such as ethanol and diethyl ether. It exhibits high volatility due to its low boiling point and can easily form flammable vapor mixtures with air.

Bromoethane is primarily used as an alkylating agent in organic synthesis for pharmaceutical and chemical manufacturing. It serves as an intermediate in the production of various chemicals, including quaternary ammonium compounds, surfactants, and pharmaceutical active ingredients. The compound is also utilized in research laboratories for methylation reactions and as a solvent in specific analytical procedures. Its reactivity makes it valuable for creating carbon-carbon and carbon-heteroatom bonds.

Bromoethane requires careful handling due to its flammable, carcinogenic, and toxic properties. Always wear appropriate personal protective equipment including chemical-resistant gloves, safety goggles, and lab coats. Work in well-ventilated areas or under fume hoods to prevent vapor inhalation. Eliminate ignition sources as the substance is highly flammable. Use grounding and bonding procedures when transferring the liquid to prevent static electricity buildup and potential fire hazards.

Bromoethane must be stored in a cool, dry, well-ventilated area away from heat sources, sparks, and open flames. Keep containers tightly sealed in their original packaging and store below 25°C to minimize vapor formation. Separate from oxidizing agents, strong bases, and reactive metals. Storage areas should have appropriate fire suppression systems and spill containment measures. Regularly inspect containers for leaks or deterioration due to the compound's volatile nature.

Bromoethane exposure requires immediate first aid measures. For skin contact, remove contaminated clothing and rinse affected areas with plenty of water for at least 15 minutes. If inhaled, move the person to fresh air and seek medical attention immediately due to potential toxicity. For eye contact, flush thoroughly with water and remove contact lenses if present. In all cases of exposure, seek professional medical advice promptly, especially given the substance's carcinogenic classification.

Bromoethane disposal must comply with local and European waste regulations as it is classified as hazardous waste. Never pour down drains or dispose of in regular trash due to its toxic and carcinogenic properties. Contact licensed hazardous waste disposal companies for proper collection and treatment. Small quantities can be neutralized through controlled incineration at authorized facilities. Always consult with waste management specialists and follow REACH regulation requirements for disposal documentation.

Bromoethane is classified under ADR Class 3 (flammable liquids), Packing Group II, requiring specific transport regulations. Use UN-approved packaging and ensure proper labeling with GHS02, GHS07, and GHS08 pictograms plus 'Danger' signal word. Transport vehicles must comply with ADR requirements including appropriate placarding and emergency equipment. Drivers need ADR certification for dangerous goods transport. Avoid transport during extreme temperatures and ensure proper documentation accompanies all shipments.

Bromoethane is subject to comprehensive European regulations under REACH and CLP classifications. It carries multiple hazard classifications including Flam. Liq. 2, Carc. 2, and Acute Tox. 4, requiring specific safety data sheets and risk assessments. While not currently listed as an SVHC (Substance of Very High Concern), its carcinogenic classification means strict workplace exposure limits apply. Users must comply with occupational health regulations and may require permits for industrial use.
