1. Pharmaceuticals
Antibiotics & Antibacterials: 4-Fluoronitrobenzene CAS 350-46-9 used in synthesizing fluoroquinolone antibiotics (e.g., ciprofloxacin derivatives).
Anticancer Agents: Intermediate for kinase inhibitors and other targeted therapies.
CNS Drugs: Building block for antipsychotics and antidepressants.
2. Agrochemicals
Herbicides & Pesticides: Key precursor for fluorinated crop-protection chemicals.
Fungicides: Enhances bioavailability and resistance to degradation.
3. Dyes & Pigments
4-Fluoronitrobenzene CAS 350-46-9 used in azo dyes and fluorescent markers due to its electron-withdrawing properties.
4. Chemical Synthesis
Nucleophilic Aromatic Substitution (SNAr): The –NO₂ group activates the ring for displacement of –F with amines, alkoxides, or thiols.
Cross-Coupling Reactions: 4-Fluoronitrobenzene used in Suzuki-Miyaura or Ullmann reactions to build complex aromatics.
5. Energetic Materials
Occasionally used in explosives research (though less common than nitro derivatives without fluorine).
1. Temperature: Store in a cool, dry place (ideally 2–8°C/36–46°F for long-term storage).
2. Light Sensitivity: Keep in amber glass bottles or opaque containers to prevent photodegradation.
3. Moisture Control: Seal tightly with PTFE-lined caps to avoid hydrolysis.
4. Inert Atmosphere: For extended storage, use nitrogen (N₂) or argon (Ar) purging to prevent oxidation.
