Chemical Structure

1H-Imidazo[4,5-b]pyridine CAS 170245-19-9 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1H-Imidazo[4,5-b]pyridine.

1H-Imidazo[4,5-b]pyridine (CAS 170245-19-9), molecular formula C6H5N3 and molecular weight 119.12 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a nitrile group, an aromatic ring system, 1H-Imidazo[4,5-b]pyridine is typically off-white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 119.12 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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

As a certified reference material (CRM), 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.
