4-Cyano-2-fluorobenzoic Acid丨CAS 164149-28-4

4-Cyano-2-fluorobenzoic acid is commonly used as an intermediate in the synthesis of pharmaceuticals, agrochemicals, and advanced organic materials. Its cyano and fluoro substituents make it a highly valuable precursor for generating heterocycles, amides, esters, and other functionalized aromatic compounds. In medicinal chemistry, it is frequently incorporated into synthetic routes targeting anti-inflammatory agents, kinase inhibitors, CNS-active molecules, and other drug candidates requiring electron-withdrawing substituent patterns to improve bioactivity or metabolic stability. In agrochemical development, it serves as a building block for designing herbicides and insecticides with enhanced potency and environmental durability. The compound is also employed in material science to produce fluorinated aromatic components used in polymers, coatings, and performance materials where chemical resistance and thermal stability are essential. Its clean reactivity profile allows efficient integration into multi-step synthetic pathways.

The key benefits of this compound arise from its strong electron-withdrawing groups, which enhance its chemical reactivity and make it suitable for diverse functional transformations. The cyano group enables nucleophilic additions, cyclizations, and reductive modifications, while the fluorine atom provides improved stability, increased lipophilicity, and tunable electronic effects desirable in drug and agrochemical design. Its defined aromatic framework supports selective substitution patterns, improving control over regioselectivity in complex syntheses. Additionally, the compound is stable, easy to handle, and compatible with a wide range of coupling, condensation, and heterocycle-forming reactions, streamlining synthetic development. These benefits make it an efficient and reliable intermediate in high-value chemical manufacturing.
