Chemical Structure
Description
The occurrence of 3,5-Difluoro-2-hydrazinylpyridine is closely related to a nitrile group, fluorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
3,5-Difluoro-2-hydrazinylpyridine (CAS 851179-06-1) is a high-purity analytical reference standard with the molecular formula C5H5F2N3 and a molecular weight of 145.11 g/mol.
The molecular framework of 3,5-Difluoro-2-hydrazinylpyridine (C5H5F2N3) is characterized by a nitrile group, fluorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
