Applications of 652-03-9
| Industry | Application | Process |
|---|---|---|
| Pharmaceutical Intermediates | Structural building block for synthesizing fluorinated quinolone antibiotics (e.g., ciprofloxacin derivatives) and antitumor agents | Serves as a key fluorinated aryl ring construction module; undergoes acid chlorination followed by condensation with amines to form amide bonds |
| Liquid Crystal Materials | Fluorinated rigid core structure for high-performance nematic liquid crystal monomers | Alkoxy or alkenyl side chains are introduced via esterification or coupling reactions to tune mesophase transition temperatures and birefringence |
| Organic Synthesis | Fluorinated building block in palladium-catalyzed cross-coupling reactions (e.g., Suzuki, Heck) | Undergoes C–C bond coupling with boronic esters or alkenes under anhydrous, oxygen-free conditions to produce polyfluorinated functional molecules |
| Polymer Materials | Building block for high-temperature- and corrosion-resistant fluorinated polyimide precursors | Reacted with diamine monomers via a two-step process (low-temperature polycondensation → high-temperature cyclization) to produce fully aromatic fluorinated polyimide films |
