methyl 5,7-dihydroxythieno[3,2-b]pyridine-6-carboxylate CAS 90691-13-7

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including methyl 5,7-dihydroxythieno[3,2-b]pyridine-6-carboxylate.

CATO supplies methyl 5,7-dihydroxythieno[3,2-b]pyridine-6-carboxylate (CAS 90691-13-7), a certified reference material (molecular formula C9H7NO4S, MW 225.22 g/mol) for analytical method development and quality control.

The molecular framework of methyl 5,7-dihydroxythieno[3,2-b]pyridine-6-carboxylate (C9H7NO4S) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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), methyl 5,7-dihydroxythieno[3,2-b]pyridine-6-carboxylate 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.
