5-(4-fluorophenyl)-2-sulfanyl-3H,4H-thieno[2,3-d]pyrimidin-4-one CAS 304684-28-4

Description

The molecular framework of 5-(4-fluorophenyl)-2-sulfanyl-3H,4H-thieno[2,3-d]pyrimidin-4-one (C12H19FN2OS2) 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

5-(4-fluorophenyl)-2-sulfanyl-3H,4H-thieno[2,3-d]pyrimidin-4-one (CAS 304684-28-4) is a high-purity analytical reference standard with the molecular formula C12H19FN2OS2 and a molecular weight of 290.42 g/mol.

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.

As a certified reference material (CRM), 5-(4-fluorophenyl)-2-sulfanyl-3H,4H-thieno[2,3-d]pyrimidin-4-one meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
