Description

As a certified reference material (CRM), 5,6-Dimethyl-2-(sulfanylmethyl)-3h,4h-thieno[2,3-d]pyrimidin-4-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.

CATO supplies 5,6-Dimethyl-2-(sulfanylmethyl)-3h,4h-thieno[2,3-d]pyrimidin-4-one (CAS 736948-79-1), a certified reference material (molecular formula C9H10N2OS2, MW 226.32 g/mol) for analytical method development and quality control.

The molecular framework of 5,6-Dimethyl-2-(sulfanylmethyl)-3h,4h-thieno[2,3-d]pyrimidin-4-one (C9H10N2OS2) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, 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.
