Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
5-(4-Methylphenyl)thieno[2,3-d]pyrimidine-4-thiol (CAS 307512-34-1), molecular formula C13H10N2S2 and molecular weight 258.36 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 5-(4-Methylphenyl)thieno[2,3-d]pyrimidine-4-thiol (C13H10N2S2) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality. 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. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
CATO manufactures 5-(4-Methylphenyl)thieno[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.
