Applications of 17823-40-4
| Industry | Application | Process |
|---|---|---|
| Pharmaceutical Intermediates | Key intermediate for synthesizing fluorinated quinolone antibiotics (e.g., ciprofloxacin derivatives) | Introduces heterocyclic structures via palladium-catalyzed cross-coupling reactions (e.g., Suzuki or Heck coupling) |
| Pesticide Development | Structural building block for novel fluorinated insecticides and fungicides | After hydrolysis of the nitrile group to carboxylic acid, condenses with amines to construct amide-based active ingredients |
| Liquid Crystal Materials | Fluorinated aromatic ring building module for high-performance liquid crystal monomers, enhancing dielectric anisotropy and clearing point | Reduces the nitrile group to an amino group, followed by reaction with anhydrides or acyl chlorides to prepare liquid crystalline diphenylacetylene compounds |
| Organic Synthesis | Multifunctional fluorinated building block for constructing complex fluorinated molecular frameworks | Participates in nucleophilic substitution, metalation–halogen exchange, and transition metal-catalyzed C–C bond formation reactions |
