Description

The occurrence of 2-(5-Methyl-1H-pyrazol-3-yl)-1H-imidazo[4,5-b]pyridine is closely related to a nitrogen-containing heterocyclic scaffold, a nitrile group in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

2-(5-Methyl-1H-pyrazol-3-yl)-1H-imidazo[4,5-b]pyridine (CAS 120800-21-7), molecular formula C10H9N5 and molecular weight 199.21 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 2-(5-Methyl-1H-pyrazol-3-yl)-1H-imidazo[4,5-b]pyridine (C10H9N5) contains a nitrogen-containing heterocyclic scaffold, a nitrile group. The molecule exhibits a degree of unsaturation (DBE) of 9.0, corresponding to approximately 9 ring(s) or double-bond equivalent(s). With a molecular weight of 199.21 g/mol, it falls into the medium-molecular-weight range. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.
