2,5-Difluoro-1H-imidazole CAS 89676-70-0

Description

The occurrence of 2,5-Difluoro-1H-imidazole is closely related to a nitrile group, fluorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies 2,5-Difluoro-1H-imidazole (CAS 89676-70-0), a certified reference material (molecular formula C3H2F2N2, MW 104.06 g/mol) for analytical method development and quality control.

Owing to a nitrile group, fluorine substitution, 2,5-Difluoro-1H-imidazole is typically white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 104.06 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.
