Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2-Mercapto-6-phenyl-3-(o-tolyl)thieno[2,3-d]pyrimidin-4(3h)-one.
CATO supplies 2-Mercapto-6-phenyl-3-(o-tolyl)thieno[2,3-d]pyrimidin-4(3h)-one (CAS 724704-32-9), a certified reference material (molecular formula C19H14N2OS2, MW 350.46 g/mol) for analytical method development and quality control.
The molecular framework of 2-Mercapto-6-phenyl-3-(o-tolyl)thieno[2,3-d]pyrimidin-4(3h)-one (C19H14N2OS2) is characterized by a steroid core, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO manufactures 2-Mercapto-6-phenyl-3-(o-tolyl)thieno[2,3-d]pyrimidin-4(3h)-one 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.
