Pyridine hydrofluoride

HF-Pyridine; Pyridinium poly(hydrogen fluoride); Pyridinium polybifluoride

CAS 62778-11-4

Chemical Formula C5H5N • (HF)x

Molecular Weight 99.1 g/mol

Pyridine hydrofluoride is a chemical complex formed by pyridine and hydrogen fluoride, often used as a fluorinating agent in organic synthesis. It's a versatile reagent, particularly for introducing fluorine into organic molecules through reactions like hydrofluorination of alkenes or substitution of hydroxyl and amino groups. While effective, it's also corrosive and requires careful handling due to the hazardous nature of hydrogen fluoride.

Industrial Uses

1. Pharmaceuticals

  • Fluorination Reagent: Pyridine hydrofluoride acts as a source of hydrogen fluoride (HF) and can be used to selectively add fluorine to different types of molecules.

2. Performance Chemicals

  • General Fluorination: HF-pyridine is a common nucleophilic fluorinating agent, meaning it introduces fluorine atoms into organic molecules where other reagents might not be effective. 
  • Beta-Fluoroamines: It's used to prepare beta-fluoroamines from amino alcohols.
