Description

Pentafluoropyridine (C₅F₅N) is a high-purity fluorinated aromatic compound with the IUPAC name 2,3,4,5,6-pentafluoropyridine (CAS No. 700-16-3). This specialty chemical features a fully fluorinated pyridine ring, offering exceptional thermal stability, chemical inertness, and unique reactivity due to its electron-deficient nature. With a molecular weight of 169.05 g/mol, it is a clear, volatile liquid (bp 83-85°C) widely used as a building block in pharmaceutical synthesis, agrochemical development, and advanced material science. Our product is rigorously tested to ensure ≥98% purity (GC), packaged under inert gas to prevent degradation, and supplied in amber glass bottles or custom bulk quantities for industrial applications. Ideal for nucleophilic substitution reactions, ligand design, and as a precursor for fluorinated polymers.

Application

Pentafluoropyridine serves as a key intermediate in the synthesis of fluorinated pharmaceuticals and agrochemicals due to its ability to undergo selective nucleophilic aromatic substitution. It is widely employed in material science for creating moisture-resistant coatings and high-performance polymers with enhanced thermal stability. Researchers also utilize it as a ligand precursor in catalysis and as a fluorinating agent in specialty chemical synthesis.
