Methyl 2-bromo-5-chlorobenzoate(CAS: 27007-53-0)

Methyl 2-bromo-5-chlorobenzoate is a white crystalline solid with a molecular weight of approximately 266.04 g/mol. It is slightly soluble in water but more soluble in organic solvents such as ethanol and acetone. This compound is moderately reactive and can undergo substitution reactions, particularly with nucleophiles. It is also prone to hydrolysis under basic conditions.

Methyl 2-bromo-5-chlorobenzoate is typically synthesized from 2-chlorobenzoic acid and methyl bromide in the presence of a base such as potassium carbonate. The reaction involves the substitution of the hydroxyl group of the benzoic acid with a bromomethyl group, followed by the displacement of the chlorine atom by bromine. This process yields a high yield of the desired product with excellent selectivity.

Methyl 2-bromo-5-chlorobenzoate is used in the pharmaceutical industry for the synthesis of certain drugs, as a precursor in the polymer industry for the production of functional polymers, and in the sensor industry for the development of gas sensors. It is also used in the semiconductor industry for specific applications in photolithography and etching processes.

When handling Methyl 2-bromo-5-chlorobenzoate, it is important to wear appropriate personal protective equipment (PPE), including gloves, safety goggles, and a lab coat. This compound should be stored in a cool, dry place away from direct sunlight. In the event of a spill, it should be contained and disposed of according to local regulations. Always refer to the Material Safety Data Sheet (MSDS) for detailed safety information and emergency procedures.
