Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 4,5,6-trichloro-2-(methylsulfonyl)pyrimidine.
4,5,6-trichloro-2-(methylsulfonyl)pyrimidine (CAS 7219-19-4) is a high-purity analytical reference standard with the molecular formula C5H3Cl3N2O2S and a molecular weight of 261.51 g/mol.
4,5,6-trichloro-2-(methylsulfonyl)pyrimidine (C5H3Cl3N2O2S) contains an amide group, a sulfone 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. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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 4,5,6-trichloro-2-(methylsulfonyl)pyrimidine 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.
