2-Bromo-3-thiophenecarboxylic acid(CAS: 24287-95-4)

2-Bromo-3-thiophenecarboxylic acid is a solid with a crystalline form. It has a molecular weight of approximately 207.02 g/mol. This compound is slightly soluble in water but more soluble in organic solvents. It is moderately reactive and can undergo bromine substitution and carboxylic acid reactions. It is a weak acid due to the presence of the carboxylic acid group.

2-Bromo-3-thiophenecarboxylic acid is typically synthesized by bromination of 3-thiophenecarboxylic acid using N-bromosuccinimide (NBS) in the presence of a suitable solvent like dichloromethane. The reaction is carried out under mild conditions to achieve good yield and selectivity. Other methods include direct bromination with bromine in the presence of a phase-transfer catalyst.

2-Bromo-3-thiophenecarboxylic acid is used in the pharmaceutical industry for the synthesis of certain drugs due to its structural properties. It is also utilized in the polymer industry for the development of advanced materials. Additionally, it finds applications in the production of sensors and as a functional group in semiconductor manufacturing processes.

When handling 2-Bromo-3-thiophenecarboxylic acid, it is essential to wear appropriate personal protective equipment (PPE) such as gloves, goggles, and a lab coat. Work in a well-ventilated area or under a fume hood to minimize exposure. Proper storage should be ensured in a cool, dry place away from direct sunlight and heat sources. In case of a spill, immediately clean up using appropriate absorbent materials and follow the safety data sheet (SDS) guidelines for disposal.
