Methyl bromo(2-chlorophenyl)acetate(CAS: 85259-19-4)

Methyl bromo(2-chlorophenyl)acetate is a crystalline solid with a molecular weight of approximately 250.72 g/mol. It has a low solubility in water but is soluble in common organic solvents like ethanol and acetone. The compound is moderately reactive, especially towards nucleophiles and reducing agents. It can undergo nucleophilic substitution and electrophilic aromatic substitution reactions.

Methyl bromo(2-chlorophenyl)acetate is synthesized through the bromination of methyl (2-chlorophenyl)acetate with an excess of bromine in the presence of a phase transfer catalyst. The reaction is carried out under anhydrous conditions to avoid side reactions. The yield is typically 80-85%, and the product is isolated by recrystallization.

Methyl bromo(2-chlorophenyl)acetate is primarily used in the pharmaceutical industry for the synthesis of certain drug intermediates. It is also used in the polymer industry for modifying polymers and in the sensor industry for developing gas-sensing materials. Additionally, it has applications in semiconductor manufacturing for etching and cleaning processes.

Handling methyl bromo(2-chlorophenyl)acetate requires appropriate personal protective equipment (PPE) such as gloves, goggles, and a lab coat. The substance should be handled in a well-ventilated area or a fume hood to avoid inhalation. Spills should be cleaned up immediately using appropriate absorbents, and the area should be flushed with water. Emergency response procedures and Material Safety Data Sheets (MSDS/SDS) should be readily accessible for reference in case of accidents.
