Description

CATO manufactures 1-(4-Chlorophenyl)-2-thioxodihydro-4,6(1H,5H)-pyrimidinedione 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.

1-(4-Chlorophenyl)-2-thioxodihydro-4,6(1H,5H)-pyrimidinedione (CAS 28921-30-4), molecular formula C10H7ClN2O2S and molecular weight 254.69 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution, 1-(4-Chlorophenyl)-2-thioxodihydro-4,6(1H,5H)-pyrimidinedione is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 254.69 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.
