Chemical Structure

1-Methyl-1H-imidazo[4,5-b]pyridin-5(4H)-one CAS 915138-52-2 chemical structure

Description

Owing to an amide group, a hydroxyl group, an ether linkage, an aromatic ring system, 1-Methyl-1H-imidazo[4,5-b]pyridin-5(4H)-one is typically off-white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 149.15 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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).

1-Methyl-1H-imidazo[4,5-b]pyridin-5(4H)-one (CAS 915138-52-2) is a high-purity analytical reference standard with the molecular formula C7H7N3O and a molecular weight of 149.15 g/mol.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

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.
