Chemical Structure
Description
2-(Allylthio)-3-(pyridin-3-yl)thieno[3,2-d]pyrimidin-4(3H)-one (CAS 338779-50-3), molecular formula C14H11N3OS2 and molecular weight 301.39 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 2-(Allylthio)-3-(pyridin-3-yl)thieno[3,2-d]pyrimidin-4(3H)-one (C14H11N3OS2) 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 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.
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-(Allylthio)-3-(pyridin-3-yl)thieno[3,2-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.
