Used primarily as an intermediate in the synthesis of pharmaceuticals, particularly in the production of fluorinated active pharmaceutical ingredients (APIs) where the difluorophenyl moiety enhances metabolic stability and bioavailability. It serves as an acylating agent in organic reactions, enabling the introduction of the 2,5-difluorophenylacetyl group to amines or alcohols, forming amides or esters. Commonly applied in the development of anti-inflammatory, antiviral, and central nervous system agents. Its fluorinated aromatic structure also makes it valuable in the design of specialty chemicals and agrochemicals requiring enhanced lipophilicity and resistance to degradation.
