Methyl 5-bromo-2-chlorobenzoate(CAS: 251085-87-7)

Methyl 5-bromo-2-chlorobenzoate is a crystalline compound with a molecular weight of approximately 264.03 g/mol. It has a low solubility in water but is more soluble in organic solvents such as ethanol and acetone. Chemically, it is moderately reactive, particularly towards nucleophiles, and can undergo substitution reactions. It is typically used in synthetic organic chemistry.

Methyl 5-bromo-2-chlorobenzoate is commonly synthesized through the bromination of 2-chlorobenzoic acid followed by esterification with methanol. This process involves the use of bromine as a brominating agent and can be carried out using a Lewis acid catalyst, such as aluminum bromide. The reaction yields a product with good selectivity, although purification steps such as recrystallization may be necessary.

Methyl 5-bromo-2-chlorobenzoate is utilized in the pharmaceutical industry for the synthesis of certain drug intermediates. It also finds applications in the polymer industry as a precursor in the production of tailored polymers. Additionally, it is used in the sensor industry for developing analytical devices and in semiconductor manufacturing as a component in certain processes.

When handling methyl 5-bromo-2-chlorobenzoate, it is important to use personal protective equipment (PPE) including gloves and safety glasses. The substance should be stored in a dry, well-ventilated area and in a fume hood during handling to minimize exposure to its vapors. In case of a spill, it should be immediately cleaned up with appropriate absorbent materials. Always refer to the Material Safety Data Sheet (MSDS) for detailed safety information and emergency procedures.
