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 bromide family. Bromoethane is classified as a flammable liquid with carcinogenic properties and acute toxicity potential. It requires careful handling due to its hazardous nature, as indicated by its Danger signal word and multiple GHS pictograms including flammability, health hazard, and exclamation mark symbols.

Bromoethane is a colorless liquid at room temperature with a characteristic sweet, chloroform-like odor. It has a boiling point of approximately 38.4°C and is denser than water. The compound is sparingly soluble in water but miscible with most organic solvents including alcohols, ethers, and hydrocarbons. Bromoethane is highly volatile and can readily evaporate at ambient temperatures, forming vapors that are heavier than air and can accumulate in low-lying areas.

Bromoethane is primarily used as an alkylating agent in organic synthesis and pharmaceutical intermediate production. It serves as a methylating reagent in chemical laboratories and industrial processes. The compound is also employed in the synthesis of various organic compounds, including pharmaceuticals, agrochemicals, and specialty chemicals. Additionally, bromoethane finds application in analytical chemistry as a derivatization agent for gas chromatography analysis and in research applications requiring ethyl group introduction into molecular structures.

Bromoethane requires strict safety protocols due to its flammable, carcinogenic, and toxic properties. Always wear appropriate personal protective equipment including chemical-resistant gloves, safety goggles, and respiratory protection in well-ventilated areas. Work in a fume hood to prevent vapor inhalation and keep away from ignition sources, heat, and open flames. Ensure emergency eyewash stations and safety showers are accessible. Ground all equipment to prevent static electricity buildup and use explosion-proof electrical equipment in work areas.

Bromoethane must be stored in a cool, dry, well-ventilated area away from heat sources, ignition sources, and direct sunlight. Use appropriate secondary containment and store in original containers with tight-fitting lids. Keep separated from oxidizing agents, strong bases, and incompatible materials. Storage areas should be equipped with fire suppression systems and maintained below 25°C. Ensure proper grounding of storage containers and implement regular inspection procedures to detect any leaks or container degradation.

Bromoethane exposure requires immediate emergency response measures. For skin contact, immediately remove contaminated clothing and wash affected area with soap and water for at least 15 minutes. In case of eye contact, flush with clean water for 15 minutes while holding eyelids open. If inhaled, move victim to fresh air immediately and provide artificial respiration if breathing has stopped. For ingestion, do not induce vomiting and seek immediate medical attention. Always contact poison control center and emergency medical services promptly.

Bromoethane disposal must comply with local, national, and international hazardous waste regulations. This substance cannot be disposed of through regular waste streams due to its toxic and carcinogenic properties. Contact licensed hazardous waste disposal companies for proper treatment and disposal. Small laboratory quantities may be neutralized through controlled chemical destruction methods. Prevent release to sewers, waterways, or soil. Maintain detailed disposal records and ensure transporters have appropriate ADR certification for hazardous materials.

Bromoethane is classified under ADR Class 3 (flammable liquids), Packing Group II, requiring specialized transport procedures. Packages must bear appropriate hazard labels including flammable liquid and health hazard markings. Use UN-approved containers and ensure proper documentation including transport documents and emergency response information. Vehicles must be equipped with appropriate fire extinguishers and emergency equipment. Drivers require ADR certification for dangerous goods transport, and routes should avoid populated areas where possible.

Bromoethane is subject to comprehensive European chemical regulations including REACH registration requirements and CLP classification obligations. As a Category 2 carcinogen, it faces strict workplace exposure limits and requires health surveillance programs. The substance must comply with industrial emissions directives and may be subject to authorization procedures under REACH. Import/export may require permits, and users must maintain safety data sheets and implement risk management measures according to regulatory requirements.
