Chemical Structure
Description
2-(1-Ethyl-1H-imidazo[4,5-c]pyridin-2-yl)acetonitrile (CAS 607368-91-2), molecular formula C10H10N4 and molecular weight 186.21 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 2-(1-Ethyl-1H-imidazo[4,5-c]pyridin-2-yl)acetonitrile (C10H10N4) contains a nitrogen-containing heterocyclic scaffold, a nitrile group. The molecule exhibits a degree of unsaturation (DBE) of 8.0, corresponding to approximately 8 ring(s) or double-bond equivalent(s). With a molecular weight of 186.21 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.
