Chemical Structure

Thieno[3,2-b]pyridin-3-ol CAS 118801-95-9 chemical structure

Description

Thieno[3,2-b]pyridin-3-ol (CAS 118801-95-9), molecular formula C7H5NOS and molecular weight 151.19 g/mol, is a CATO reference standard with documented purity and traceability.

Thieno[3,2-b]pyridin-3-ol (C7H5NOS) contains an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, an aromatic ring system. Its physicochemical properties are representative of its class; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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), Thieno[3,2-b]pyridin-3-ol 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.
