4-AMINO-2,3,5,6-TETRAFLUOROPYRIDINE: Technical Overview and Synthesis Pathways

1. Basic Information & Specifications

Parameter Value
CAS Number 1682-20-8
Chemical Formula C5H2F4N2
IUPAC Name 2,3,5,6-Tetrafluoropyridin-4-amine
Synonyms
  • 4-Amino-2,3,5,6-tetrafluoropyridine
  • 2,3,5,6-Tetrafluoro-4-pyridinamine

2. Synthesis Methods

Primary Synthetic Routes:

  1. Route 1: From Pentafluoropyridine
    Pentafluoropyridine undergoes selective amination at the 4-position via nucleophilic aromatic substitution. This reaction typically employs ammonia or amine derivatives under controlled temperature (80-120°C) in polar aprotic solvents.
  2. Route 2: Pentafluoropyridine with N-Methylhydroxylamine Hydrochloride
    This method utilizes N-methylhydroxylamine hydrochloride as the aminating agent in dimethylformamide (DMF) at elevated temperatures. The reaction achieves 60-75% yield with optimized stoichiometric ratios.

Note: Reaction conditions require strict control of moisture and oxygen levels. Detailed protocols should be validated through laboratory testing.

3. Key Applications

  • Pharmaceutical intermediate for fluorinated drug candidates
  • Agrochemical precursor for herbicidal formulations
  • Building block in specialty polymer synthesis
  • Ligand precursor in organometallic catalysis

4. Safety Considerations

  • Potential respiratory irritant (use fume hood)
  • Thermal decomposition may release toxic fluorides
  • Incompatible with strong oxidizers and acids
  • Store under inert atmosphere at 2-8°C
