Bromomethylbenzene

Bromomethylbenzene is an aromatic organobromine compound with the molecular formula C7H7Br and CAS number 100-39-0. It consists of a benzene ring substituted with a bromomethyl group (-CH2Br). With a molecular weight of 171.03 g/mol, this substance is classified as a moderate health hazard, causing skin and eye irritation and specific target organ toxicity. It carries the GHS07 pictogram and Warning signal word under CLP regulation.

Bromomethylbenzene is typically a colorless to pale yellow liquid at room temperature with a characteristic aromatic odor. As an aromatic halide, it has limited solubility in water but dissolves readily in organic solvents such as alcohols, ethers, and hydrocarbons. The compound exhibits moderate volatility and density higher than water due to the presence of the bromine atom, which contributes to its molecular weight of 171.03 g/mol.

Bromomethylbenzene serves primarily as an intermediate in organic synthesis and pharmaceutical manufacturing. It is commonly used in the production of various benzyl derivatives, pharmaceutical compounds, and specialty chemicals. The compound acts as an alkylating agent in chemical reactions and finds applications in the synthesis of quaternary ammonium compounds, pharmaceutical intermediates, and other fine chemicals in research and industrial settings.

Bromomethylbenzene requires careful handling with appropriate personal protective equipment including chemical-resistant gloves, safety goggles, and protective clothing to prevent skin and eye contact. Work should be conducted in well-ventilated areas or under fume hoods to avoid inhalation exposure. Given its STOT SE 3 classification and irritant properties, minimize direct contact and ensure proper ventilation. Always follow established safety protocols and have emergency procedures readily available.

Bromomethylbenzene should be stored in tightly sealed containers in a cool, dry, well-ventilated area away from heat sources, direct sunlight, and incompatible materials. Keep containers in secondary containment to prevent spills and ensure proper labeling with hazard information. Store separately from strong bases, oxidizing agents, and reactive metals. Maintain storage temperatures as recommended by the supplier and regularly inspect containers for signs of deterioration or leakage.

Bromomethylbenzene contact requires immediate action: for skin contact, remove contaminated clothing and wash affected area thoroughly with soap and water for at least 15 minutes. In case of eye contact, rinse immediately with clean water for 15 minutes while holding eyelids open. If inhaled, move to fresh air immediately. Remove contaminated clothing and wash before reuse. Seek medical attention if irritation persists or if large amounts were involved in the exposure.

Bromomethylbenzene disposal must comply with local, national, and international waste regulations as it is classified as hazardous waste. Do not dispose of in regular trash or pour down drains. Contact licensed hazardous waste disposal companies for proper treatment and disposal. Small laboratory quantities may be suitable for incineration at authorized facilities. Always consult current waste disposal regulations and maintain proper documentation for waste tracking and compliance purposes.

Bromomethylbenzene is classified under ADR as Class 6.1 (toxic substances), Packing Group II, requiring specific transport protocols for dangerous goods. Packages must bear appropriate hazard labels and proper shipping names. Drivers need ADR certification for toxic substance transport. Use UN-approved packaging and ensure proper documentation including transport documents and emergency response information. Comply with quantity limitations and routing restrictions as specified in ADR regulations.

Bromomethylbenzene is subject to various chemical regulations including REACH registration requirements for import/manufacture in the EU and CLP classification obligations. It is not currently listed as a Substance of Very High Concern (SVHC) under REACH. Users must comply with workplace safety regulations, transport requirements under ADR, and proper hazard communication through safety data sheets. Always verify current regulatory status as requirements may change over time.
