Thieno[2,3-d]pyridazin-4(5H)-one CAS 824-23-7

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Thieno[2,3-d]pyridazin-4(5H)-one.

CATO supplies Thieno[2,3-d]pyridazin-4(5H)-one (CAS 824-23-7), a certified reference material (molecular formula C6H4N2OS, MW 152.17 g/mol) for analytical method development and quality control.

The molecular framework of Thieno[2,3-d]pyridazin-4(5H)-one (C6H4N2OS) is characterized by an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, an aromatic ring system. 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), Thieno[2,3-d]pyridazin-4(5H)-one 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.
