Description
4-(2,3,4-Trimethoxyphenyl)-3h,4h,5h,6h,7h-imidazo[4,5-c]pyridine-6-carboxylic acid (CAS 1214000-37-9), molecular formula C16H19N3O5 and molecular weight 333.34 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 4-(2,3,4-Trimethoxyphenyl)-3h,4h,5h,6h,7h-imidazo[4,5-c]pyridine-6-carboxylic acid (C16H19N3O5) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage. 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 333.34 g/mol, it falls into the moderately-high-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.
