Cas no 62778-11-4 (Pyridinium Poly(hydrogenfluoride))

Pyridinium Poly(hydrogenfluoride) is a stable, non-volatile alternative to anhydrous hydrogen fluoride (HF), offering enhanced safety and handling convenience. This reagent consists of a pyridinium cation paired with a polymeric hydrogen fluoride anion, providing controlled reactivity while maintaining the fluorination capabilities of HF. Its solid or viscous liquid form minimizes hazardous fumes, reducing exposure risks. Commonly used in organic synthesis, it facilitates fluorinations, deprotections, and rearrangements with high selectivity. The polymeric structure ensures gradual HF release, improving reaction control and reproducibility. Suitable for laboratory and industrial applications, it is particularly valuable where precise fluorination or acid-mediated transformations are required. Compatible with standard glassware, it simplifies operational procedures compared to traditional HF.
