Chemical Structure

Thiazolo[4,5-b]pyridine CAS 273-98-3 chemical structure

Description

Thiazolo[4,5-b]pyridine (CAS 273-98-3) is a high-purity analytical reference standard with the molecular formula C6H4N2S and a molecular weight of 136.17 g/mol.

Structurally, Thiazolo[4,5-b]pyridine (C6H4N2S) contains a nitrile group, sulfur-containing functionality, an aromatic ring system. 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 136.17 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).

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.

As a certified reference material (CRM), Thiazolo[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.
