2,4-Difluorobenzonitrile Cas 3939-09-1

Pharmaceutical intermediates: Key building blocks for fluorine-containing drugs, used in the synthesis of intermediates for kinase inhibitors, anti-tumor agents, and psychiatric medications; fluorinated aromatic structures enhance metabolic stability.
Agrochemical intermediates: Used to synthesize fluorine-containing fungicides and herbicides; fluorine substitution improves efficacy and rain-fastness.
Organic synthesis: Raw materials for aromatic nucleophilic substitution and coupling reactions; the cyano group can be converted into carboxylic acid, amide, or amine functional groups.
Functional new materials: Precursors for the synthesis of liquid crystal monomers, organic semiconductors, and polymer modifications.
