Chemical Structure
Description
CATO supplies 1-Chloro-3-methyl-1H-pyrimidine-2,4-dione (CAS CATO-C3D-2079), a certified reference material (molecular formula C5H5ClN2O2, MW 160.56 g/mol) for analytical method development and quality control.
1-Chloro-3-methyl-1H-pyrimidine-2,4-dione (C5H5ClN2O2) contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO manufactures 1-Chloro-3-methyl-1H-pyrimidine-2,4-dione 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.
