Bromobenzene

Bromobenzene is an aromatic halogenated hydrocarbon with the molecular formula C6H5Br and CAS number 108-86-1. It consists of a benzene ring with one bromine atom substituted for a hydrogen atom. With a molecular weight of 157.01 g/mol, bromobenzene appears as a colorless to pale yellow liquid with a characteristic aromatic odor. It is classified as a flammable liquid and requires careful handling due to its potential skin irritation properties and environmental impact.

Bromobenzene is a colorless to pale yellow liquid at room temperature with a distinctive sweet, aromatic odor similar to benzene. It has a boiling point of approximately 156°C and a density higher than water. The compound is practically insoluble in water but readily soluble in organic solvents such as ethanol, ether, and acetone. It exhibits typical aromatic compound behavior and is stable under normal conditions but should be protected from strong oxidizing agents.

Bromobenzene is primarily used as an intermediate in organic synthesis for pharmaceutical and agrochemical manufacturing. It serves as a precursor for the production of various substituted aromatic compounds through nucleophilic substitution reactions. The compound is also utilized in the synthesis of dyes, perfumes, and other specialty chemicals. Additionally, bromobenzene finds application as a solvent in specific chemical processes and as a reagent in laboratory research for organic chemistry applications.

Bromobenzene requires careful handling with appropriate personal protective equipment including chemical-resistant gloves, safety goggles, and protective clothing to prevent skin contact. Work should be conducted in well-ventilated areas or under a fume hood to avoid inhalation of vapors. Keep away from ignition sources, heat, and sparks as it is classified as a flammable liquid. Avoid contact with skin and eyes, and ensure emergency wash facilities are readily available in the work area.

Bromobenzene should be stored in a cool, dry, well-ventilated area away from heat sources, sparks, and open flames. Use appropriate secondary containment and store in compatible containers, preferably original packaging. Keep away from strong oxidizing agents and incompatible materials. Storage areas should be equipped with appropriate fire suppression systems and spill control measures. Ensure containers are properly labeled and access is restricted to authorized personnel only.

In case of skin contact with bromobenzene, immediately remove contaminated clothing and wash the affected area thoroughly with soap and water for at least 15 minutes. For eye contact, flush immediately with clean water for at least 15 minutes and seek medical attention. If inhaled, move the person to fresh air and monitor breathing. If swallowed, do not induce vomiting and seek immediate medical attention. Always consult a physician if symptoms persist or worsen.

Bromobenzene must be disposed of as hazardous waste in accordance with local, national, and international regulations. The compound cannot be discharged into sewers, waterways, or soil due to its environmental classification. Contact licensed waste disposal companies for proper collection and treatment. Small quantities may be incinerated at high temperatures in approved facilities. Always consult current waste disposal regulations and obtain proper waste codes before disposal.

Bromobenzene is classified under ADR as Class 3 (Flammable Liquids), Packing Group III for transportation purposes. It must be packaged in approved containers and properly labeled with appropriate hazard markings and documentation. Transport vehicles should be equipped with appropriate safety equipment and drivers must hold valid dangerous goods certifications. Shipping papers must accompany the shipment with correct technical names, UN numbers, and emergency contact information.

Bromobenzene is subject to various chemical regulations including REACH registration requirements in Europe and CLP classification and labeling obligations. It is not currently listed as a Substance of Very High Concern (SVHC). The compound must be handled according to occupational safety regulations and environmental protection laws. Users must maintain safety data sheets, conduct risk assessments, and implement appropriate control measures. Import/export may require additional permits depending on destination countries.
