5,6-Dimethylthieno[2,3-d]pyrimidine-4-thiol CAS 307512-33-0

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 5,6-Dimethylthieno[2,3-d]pyrimidine-4-thiol.

CATO supplies 5,6-Dimethylthieno[2,3-d]pyrimidine-4-thiol (CAS 307512-33-0), a certified reference material (molecular formula C8H8N2S2, MW 196.29 g/mol) for analytical method development and quality control.

The molecular framework of 5,6-Dimethylthieno[2,3-d]pyrimidine-4-thiol (C8H8N2S2) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality. 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.

CATO manufactures 5,6-Dimethylthieno[2,3-d]pyrimidine-4-thiol under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
