3-Bromo-5-chlorophenol(CAS: 56962-04-0)

3-Bromo-5-chlorophenol (CAS: 56962-04-0) is a white to off-white crystalline solid with a molecular weight of approximately 227.01 g/mol. It is slightly soluble in water but soluble in organic solvents like ethanol and acetone. Chemically, it is highly reactive, particularly with nucleophiles, and can undergo electrophilic aromatic substitution reactions.

3-Bromo-5-chlorophenol is typically synthesized by the bromination of 5-chlorophenol. This reaction is often catalyzed by iron(III) bromide, with a yield of around 85%. The reaction is selective towards the ortho position, making it a useful intermediate in organic synthesis.

3-Bromo-5-chlorophenol (CAS: 56962-04-0) is used in the pharmaceutical industry for the synthesis of certain drugs and in the production of dyes and pigments. It is also utilized in the polymer industry for developing functional materials and in the sensor industry for its sensitivity to specific analytes.

When handling 3-Bromo-5-chlorophenol (CAS: 56962-04-0), it is crucial to use appropriate personal protective equipment (PPE) such as gloves, goggles, and a lab coat. Work should be conducted in a well-ventilated area or fume hood to minimize inhalation of vapors. In case of a spill, immediately clean up using appropriate absorbents and follow the safety data sheet (SDS) guidelines for disposal.
