4-(Acetoxymethyl)-3-bromobenzoic acid(CAS: 90772-73-9)

4-(Acetoxymethyl)-3-bromobenzoic acid is a white or off-white crystalline solid with a molecular weight of approximately 286.04 g/mol. It is poorly soluble in water but soluble in most organic solvents. This compound exhibits moderate reactivity, particularly towards nucleophiles and bases, and is often used in organic synthesis due to its functional groups.

4-(Acetoxymethyl)-3-bromobenzoic acid can be synthesized through a multi-step reaction starting from 3-bromobenzoic acid. The key steps include esterification of the carboxylic acid group to form the acetate ester, followed by bromination of the hydroxyl group at the methyl position. This process typically involves the use of acetic anhydride and a suitable base as a catalyst.

4-(Acetoxymethyl)-3-bromobenzoic acid is primarily used in the pharmaceutical industry for the synthesis of various drugs and intermediates. It is also used in the polymer industry for modifying polymer properties and in the sensor industry for developing sensitive detection systems. Its reactivity towards nucleophiles makes it valuable in semiconductor applications as well.

When handling 4-(Acetoxymethyl)-3-bromobenzoic acid, it is essential to wear appropriate personal protective equipment (PPE), including gloves, goggles, and a lab coat. Work should be conducted in a well-ventilated area or fume hood due to its potential reactivity. Spills should be cleaned up carefully using appropriate techniques and materials. Always refer to the Safety Data Sheet (SDS) for detailed handling and disposal instructions.
