2,4-Difluoropyridine 1-Oxide CAS 303154-04-3

Description

The occurrence of 2,4-Difluoropyridine 1-Oxide is closely related to an amide group, a hydroxyl group, an ether linkage, fluorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies 2,4-Difluoropyridine 1-Oxide (CAS 303154-04-3), a certified reference material (molecular formula C5H3F2NO, MW 131.08 g/mol) for analytical method development and quality control.

Structurally, 2,4-Difluoropyridine 1-Oxide (C5H3F2NO) contains an amide group, a hydroxyl group, an ether linkage, fluorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 4.0, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 131.08 g/mol, it falls into the low-molecular-weight range. 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).

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
