4-Bromo-2-chloroaniline(CAS: 38762-41-3)

4-Bromo-2-chloroaniline (CAS: 38762-41-3) is a white to off-white crystalline solid with a molecular weight of approximately 215.01 g/mol. It has a low solubility in water but is more soluble in organic solvents like ethanol and acetone. The compound is moderately reactive and can undergo aromatic substitution reactions. It is often used as a precursor in the synthesis of dyes and pharmaceuticals.

4-Bromo-2-chloroaniline (CAS: 38762-41-3) is typically synthesized by the reaction of 2-chloroaniline with bromine in the presence of a solvent like glacial acetic acid. This process provides good selectivity and yield. Catalysts such as iron (III) chloride can be used to improve the reaction rate. The product is then purified by recrystallization or distillation.

4-Bromo-2-chloroaniline (CAS: 38762-41-3) is primarily used in the pharmaceutical and dye industries. It serves as a key intermediate in the synthesis of various medicinally important compounds and pigments. Additionally, it has applications in the polymer and semiconductor industries for the development of advanced materials.

When handling 4-Bromo-2-chloroaniline (CAS: 38762-41-3), it is crucial to wear appropriate personal protective equipment (PPE) such as gloves, goggles, and a lab coat. Work should be conducted in a well-ventilated area or a fume hood. Spills should be cleaned up promptly using appropriate absorbents. Always refer to the Material Safety Data Sheet (MSDS) or Safety Data Sheet (SDS) for detailed safety information and emergency procedures.
