Chemical Structure
Description
3,8-Dimethyl-2-thioxo-2,3-dihydro-1H-purin-6(7H)-one (CAS 91725-06-3), molecular formula C7H8N4OS and molecular weight 196.23 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 3,8-Dimethyl-2-thioxo-2,3-dihydro-1H-purin-6(7H)-one (C7H8N4OS) 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. 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 3,8-Dimethyl-2-thioxo-2,3-dihydro-1H-purin-6(7H)-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.
