Chemical Structure

2-Ethyl-1H-imidazo[4,5-b]pyridine CAS 68175-08-6 chemical structure

Description

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

CATO supplies 2-Ethyl-1H-imidazo[4,5-b]pyridine (CAS 68175-08-6), a certified reference material (molecular formula C8H9N3, MW 147.18 g/mol) for analytical method development and quality control.

Structurally, 2-Ethyl-1H-imidazo[4,5-b]pyridine (C8H9N3) contains a nitrogen-containing heterocyclic scaffold, a nitrile group. The molecule exhibits a degree of unsaturation (DBE) of 6.0, corresponding to approximately 6 ring(s) or double-bond equivalent(s). With a molecular weight of 147.18 g/mol, it falls into the low-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).

As a certified reference material (CRM), 2-Ethyl-1H-imidazo[4,5-b]pyridine meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
