6-(2,4-Difluorophenyl)-2-thioxo-2,3-dihydropyrimidin-4(1H)-one CAS 1493941-32-4

Description

6-(2,4-Difluorophenyl)-2-thioxo-2,3-dihydropyrimidin-4(1H)-one (CAS 1493941-32-4), molecular formula C10H6F2N2OS and molecular weight 240.23 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, fluorine substitution, 6-(2,4-Difluorophenyl)-2-thioxo-2,3-dihydropyrimidin-4(1H)-one is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 240.23 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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), 6-(2,4-Difluorophenyl)-2-thioxo-2,3-dihydropyrimidin-4(1H)-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.
