Chemical Structure
Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
2,4-Dioxo-1,2,3,4-tetrahydropyrimidine-5-sulfonyl chloride (CAS 28485-18-9), molecular formula C4H3ClN2O4S and molecular weight 210.60 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 2,4-Dioxo-1,2,3,4-tetrahydropyrimidine-5-sulfonyl chloride (C4H3ClN2O4S) is characterized by a carbohydrate-derived structure, an amide group, a sulfone group, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, 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.
CATO manufactures 2,4-Dioxo-1,2,3,4-tetrahydropyrimidine-5-sulfonyl chloride 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.
