2-Bromo-4-chlorobenzoic acid(CAS: 936-08-3)

2-Bromo-4-chlorobenzoic acid is a crystalline solid with a molecular weight of approximately 234.01 g/mol. It is poorly soluble in water but more soluble in organic solvents like ethanol and acetone. Chemically, it reacts readily with bases, showing acidity due to the carboxylic acid group, and it can undergo halogenation and sulfonation reactions.

2-Bromo-4-chlorobenzoic acid is typically synthesized by bromination of 4-chlorobenzoic acid using N-bromosuccinimide (NBS) in the presence of a photoinitiator under UV light. The reaction is selective and yields a high percentage of the desired product.

2-Bromo-4-chlorobenzoic acid is used in the pharmaceutical industry as an intermediate for the synthesis of various drugs. It also finds applications in the production of organic pigments and as a precursor in the synthesis of certain polymers and sensors.

When handling 2-Bromo-4-chlorobenzoic acid, it is important to wear appropriate personal protective equipment (PPE) such as gloves, goggles, and a lab coat. Work in a fume hood to minimize exposure to fumes and vapors. Keep the compound away from heat and sources of ignition. In case of a spill, immediately clean up using appropriate safety measures and refer to the Material Safety Data Sheet (MSDS/SDS) for further guidance.
