5-Bromo-2-chloronicotinic acid(CAS: 29241-65-4)

5-Bromo-2-chloronicotinic acid is a crystalline solid with a molecular weight of approximately 211.01 g/mol. It has a solubility of about 0.3 g/L in water at 25°C. The compound is moderately reactive, showing basic properties due to the carboxylic acid functionality. It does not decompose under normal storage conditions but may undergo hydrolysis at elevated temperatures or in the presence of moisture.

5-Bromo-2-chloronicotinic acid can be synthesized by bromination of 2-chloronicotinic acid. This is typically achieved through a reaction with bromine in the presence of a sulfuric acid catalyst. The process involves careful control of temperature and reaction time to achieve high yield and selectivity. The purity of the compound can be enhanced through recrystallization from suitable solvents.

5-Bromo-2-chloronicotinic acid is used in pharmaceuticals for the synthesis of certain drugs, particularly those that require specific functional groups for further chemical modifications. It is also used in the electronics industry for semiconductor applications and in the development of advanced polymers. Additionally, it finds applications in the production of sensors and other specialized chemical compounds.

When handling 5-Bromo-2-chloronicotinic acid, it is essential to wear appropriate personal protective equipment (PPE), including gloves, safety goggles, and a lab coat. Store the compound in a dry, well-ventilated area away from heat sources and incompatible materials. Handle in a fume hood to avoid exposure to bromine and chlorine vapors. In case of spills, immediately clean up using appropriate absorbent materials and dispose of waste according to local regulations. Always consult the Safety Data Sheet (SDS) for detailed handling and disposal instructions.
