4,5,6,7-Tetrahydro-3H-imidazo[4,5-c]pyridine-6-carboxylic acid dihydrate CAS 5145-41-5

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 4,5,6,7-Tetrahydro-3H-imidazo[4,5-c]pyridine-6-carboxylic acid dihydrate.

4,5,6,7-Tetrahydro-3H-imidazo[4,5-c]pyridine-6-carboxylic acid dihydrate (CAS 5145-41-5), molecular formula C7H9N3O2H2O and molecular weight 185.18 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage, 4,5,6,7-Tetrahydro-3H-imidazo[4,5-c]pyridine-6-carboxylic acid dihydrate is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 185.18 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
