2-(Difluoromethyl)-3H-imidazo[4,5-b]pyridine CAS 1247527-34-9 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2-(Difluoromethyl)-3H-imidazo[4,5-b]pyridine.

2-(Difluoromethyl)-3H-imidazo[4,5-b]pyridine (CAS 1247527-34-9), molecular formula C7H5F2N3 and molecular weight 169.13 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 2-(Difluoromethyl)-3H-imidazo[4,5-b]pyridine (C7H5F2N3) contains a nitrile group, fluorine substitution, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 6.0, corresponding to approximately 6 ring(s) or double-bond equivalent(s). With a molecular weight of 169.13 g/mol, it falls into the medium-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.

As a certified reference material (CRM), 2-(Difluoromethyl)-3H-imidazo[4,5-b]pyridine meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
