5-Fluoro-2-(trifluoromethyl)benzoic acid(CAS: 654-99-9)

5-Fluoro-2-(trifluoromethyl)benzoic acid is a crystalline solid with a molecular weight of approximately 267.07 g/mol. It is slightly soluble in water and ethanol. Chemically, it is reactive with bases and can form salts. It is stable under normal conditions but requires care in concentrated acid environments.

5-Fluoro-2-(trifluoromethyl)benzoic acid is typically synthesized via the Friedel-Crafts alkylation of benzoic acid with trifluoromethyl triflate in the presence of aluminum chloride as a catalyst. The reaction yields the compound with high selectivity, and purification can be achieved through recrystallization.

5-Fluoro-2-(trifluoromethyl)benzoic acid is used in the pharmaceutical industry for the synthesis of drugs, particularly those that require specific substituents for bioactivity. It also finds applications in the polymer industry for the development of advanced materials and in chemical sensors for detecting specific analytes.

When handling 5-Fluoro-2-(trifluoromethyl)benzoic acid, it is important to wear appropriate personal protective equipment (PPE) including gloves and goggles. The compound should be stored in a fume hood to minimize exposure. Spills should be cleaned up using appropriate absorbent materials, and the area should be ventilated. Always refer to the Safety Data Sheet (SDS) for detailed safety information.
