Bromomethylbenzene

Bromomethylbenzene is an aromatic organobromine compound with the molecular formula C7H7Br and CAS number 100-39-0. This chemical features a benzene ring with a bromomethyl substituent, giving it a molecular weight of 171.03 g/mol. It is classified as a hazardous substance with moderate toxicity, requiring careful handling due to its potential to cause skin and eye irritation as well as specific target organ toxicity.

Bromomethylbenzene is typically a colorless to pale yellow liquid at room temperature with a characteristic aromatic odor. The compound has a molecular weight of 171.03 g/mol and contains a reactive bromomethyl group attached to a benzene ring. It exhibits limited solubility in water but dissolves readily in organic solvents such as alcohols, ethers, and aromatic hydrocarbons, making it suitable for various organic synthesis applications.

Bromomethylbenzene serves primarily as an intermediate in organic synthesis and pharmaceutical manufacturing. It is commonly used in the production of various chemical compounds through nucleophilic substitution reactions, where the bromine atom can be replaced with other functional groups. The compound finds applications in the synthesis of specialty chemicals, pharmaceutical intermediates, and research chemicals in laboratory settings and industrial processes.

Safe handling of bromomethylbenzene requires appropriate personal protective equipment including chemical-resistant gloves, safety goggles, and protective clothing. Work should be conducted in well-ventilated areas or under fume hoods to prevent inhalation exposure. Avoid direct skin and eye contact, as the substance can cause irritation. Use proper laboratory techniques, ensure adequate ventilation, and have emergency procedures in place for potential exposure incidents.

Bromomethylbenzene should be stored in tightly sealed containers in a cool, dry, well-ventilated area away from direct sunlight and heat sources. Keep the substance away from incompatible materials such as strong oxidizing agents and bases that could react with the bromomethyl group. Storage areas should be equipped with appropriate spill containment measures and maintained at stable temperatures to prevent degradation or unwanted reactions.

In case of skin contact with bromomethylbenzene, immediately remove contaminated clothing and wash the affected area thoroughly with soap and water for at least 15 minutes. For eye contact, rinse immediately with clean water for 15-20 minutes and seek medical attention. If inhaled, move the person to fresh air and seek medical advice if symptoms persist. Remove contaminated clothing and wash before reuse.

Proper disposal of bromomethylbenzene must comply with local and international hazardous waste regulations. The substance should not be discharged into sewers or the environment. Contact licensed hazardous waste disposal companies for appropriate treatment and disposal methods. Small laboratory quantities may be collected for incineration at specialized facilities equipped to handle organobromine compounds while preventing the formation of harmful by-products.

Bromomethylbenzene is classified under ADR Class 6.1 (toxic substances) Packing Group II, requiring specific transport procedures for hazardous materials. The substance must be packaged in approved containers with proper labeling including the GHS07 pictogram and 'Warning' signal word. Transportation should follow ADR regulations for toxic substances, including proper documentation, vehicle placarding, and driver certification for hazardous materials transport.

Bromomethylbenzene is subject to various chemical regulations including REACH registration requirements in Europe and CLP classification as STOT SE 3, Skin Irritant 2, and Eye Irritant 2. While not currently listed as an SVHC (Substance of Very High Concern), it requires proper safety data sheets, hazard communication, and compliance with occupational exposure limits. Users must follow proper risk assessment and management measures under applicable chemical safety regulations.
