2,3,4-trifluoro-5-nitrobenzoic acid(CAS: 197520-71-1)

2,3,4-Trifluoro-5-nitrobenzoic acid is a crystalline solid with a molecular weight of approximately 236.05 g/mol. It is slightly soluble in water and has a low solubility in organic solvents. The compound is highly reactive towards nucleophiles due to its aromatic nitro group. It exhibits acidic properties, particularly when dissociating in aqueous solutions.

2,3,4-Trifluoro-5-nitrobenzoic acid can be synthesized by the nitration of 2,3,4-trifluorobenzoic acid using concentrated nitric acid and sulfuric acid as a catalyst. The reaction is performed under nitration conditions, ensuring high selectivity and yield. Post-nitration, the product is isolated and purified through recrystallization.

2,3,4-Trifluoro-5-nitrobenzoic acid finds applications in the pharmaceutical industry for the synthesis of intermediates and active pharmaceutical ingredients. It is also used in the polymer industry for the preparation of fluorinated polymers. Additionally, it plays a role in the development of sensors and as an analytical reagent due to its reactivity and stability.

When handling 2,3,4-trifluoro-5-nitrobenzoic acid, it is essential to use proper personal protective equipment (PPE) such as gloves, goggles, and a lab coat. Work should be conducted in a well-ventilated fume hood to prevent inhalation of fumes. In case of a spill, immediately use a spill kit and follow the emergency procedures outlined in the Safety Data Sheet (SDS).
