Comprehensive Guide to 2-Amino-3-Nitro-5-Fluoropyridine

1. Product Overview & Specifications

Parameter Value
CAS No. 212268-12-7
Molecular Formula C5H4FN3O2
Molecular Weight 157.10 g/mol
Purity ≥98%
Storage 2-8°C, protected from light
Appearance Light yellow crystalline solid

Comparative Advantages: This compound exhibits superior thermal stability compared to non-fluorinated analogs, with a decomposition temperature exceeding 200°C. Its nitro and amino groups enable versatile derivatization for specialized applications.

2. Key Applications

Pharmaceutical Development

  • Intermediate for kinase inhibitors and antiviral agents
  • Building block for PET radiotracers targeting neurological disorders

Agrochemical Research

  • Core structure for novel neonicotinoid insecticides
  • Precursor for fungicides with enhanced leaf adhesion

Material Science

  • Ligand precursor for transition metal complexes
  • Monomer for conductive polymer synthesis

3. Usage Guidelines

Handling Recommendations

  1. Use nitrogen atmosphere for long-term storage (>6 months)
  2. Dissolve in DMF or DMSO at ≤50 mg/mL for reaction systems
  3. Maintain pH 6-8 in aqueous solutions to prevent decomposition

Synthetic Protocols

Chichibabin Reaction Optimization: Achieve 82% yield using NH3/KNO3 at 110°C with 18-hour reaction time. Post-synthesis purification requires column chromatography (silica gel, ethyl acetate/hexane 3:7).

4. Case Studies

Case 1: Agrochemical Formulation (South China Agricultural University)

  • Application: Development of broad-spectrum fungicide
  • Result: 97.8% purity achieved via optimized “one-pot” diazotization
  • Scale: 500g batch production

Case 2: Pharmaceutical Intermediate Synthesis (Leyan Pharma)

  • Application: EGFR inhibitor precursor
  • Process: Three-step functionalization with 73% overall yield
  • Quality: Consistently meets USP Class 2 impurity standards

5. Technical Support & Customization

Our technical team provides:

  • Bulk synthesis up to 50kg/month
  • Isotope-labeled derivatives (13C, 15N)
