(2,5-Difluorophenyl)acetic acid(CAS: 85068-27-5)

(2,5-Difluorophenyl)acetic acid is a white crystalline solid with a molecular weight of approximately 182.08 g/mol. It exhibits low water solubility but is more soluble in organic solvents like ethanol and acetone. This compound shows moderate reactivity, particularly in acid-catalyzed reactions and esterification. It is stable under normal conditions but should be stored in a cool, dry place away from strong acids and bases.

(2,5-Difluorophenyl)acetic acid is commonly synthesized through the acetylation of 2,5-difluorophenol with acetic anhydride in the presence of a catalyst such as pyridine. The reaction proceeds under mild conditions, providing a yield of around 85-90%. The product is purified by recrystallization from a suitable solvent to obtain the white crystalline form.

(2,5-Difluorophenyl)acetic acid finds applications in various industries. It is used as a precursor in the pharmaceutical industry for the synthesis of drug intermediates. In the polymer industry, it is utilized in the development of functional polymers. Additionally, it is employed in the production of sensors and as a material for semiconductors due to its chemical properties.

When handling (2,5-Difluorophenyl)acetic acid, it is essential to wear appropriate personal protective equipment (PPE), including gloves, goggles, and a lab coat. Work must be conducted in a well-ventilated fume hood to minimize inhalation risks. Spills should be immediately neutralized with a suitable base and cleaned up using absorbent materials. Always refer to the safety data sheet (SDS) for detailed handling instructions and emergency procedures.
