2,3,5-trifluorobenzoic acid; CAS No.: 654-87-5;2,3,5-trifluorobenzoic acid. PROPERTIES: 2,3,5-trifluorobenzoic acid is a fluorinated aromatic carboxylic acid with molecular formula C7H3F3O2. It typically exists as a white to off-white crystalline powder with a melting point of approximately 105-110 C. The compound has limited water solubility but dissolves in basic aqueous solutions. It exhibits moderate thermal stability but may decompose when exposed to high temperatures or strong bases, releasing toxic fluorine-containing fumes. Proper storage involves keeping it in tightly sealed containers below 30 C, protected from moisture and heat. APPLICATIONS: In pharmaceutical research, this compound serves as a lead structure for developing antimicrobial and anticancer agents. The trifluoro substitution provides electron-withdrawing effects that enhance binding to biological targets, while the carboxylic acid group forms the pharmacophore essential for activity (European Journal of Medicinal Chemistry). In materials science, 2,3,5-trifluorobenzoic acid contributes to the creation of functional organic materials with tailored electronic properties. Its fluorinated aromatic core influences the electronic characteristics of derived materials, useful in optoelectronic applications such as organic field-effect transistors (Journal of Materials Chemistry C). The carboxylic acid group enables formation of coordination polymers or metal-organic frameworks with potential applications in gas storage or catalysis (Chemistry of Materials).
