Chemical Structure
Description
CATO supplies 3-Ethyl-2-((3-fluorobenzyl)thio)thieno[3,2-d]pyrimidin-4(3H)-one (CAS 1089618-38-1), a certified reference material (molecular formula C15H13FN2OS2, MW 320.40 g/mol) for analytical method development and quality control.
The molecular framework of 3-Ethyl-2-((3-fluorobenzyl)thio)thieno[3,2-d]pyrimidin-4(3H)-one (C15H13FN2OS2) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, fluorine substitution. 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 presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
