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.
CATO supplies 8-Chloro-1,3,9-trimethyl-1H-purine-2,6(3H,9H)-dione (CAS 4921-53-3), a certified reference material (molecular formula C8H9ClN4O2, MW 228.64 g/mol) for analytical method development and quality control.
8-Chloro-1,3,9-trimethyl-1H-purine-2,6(3H,9H)-dione (C8H9ClN4O2) contains a nitrogen-containing heterocyclic scaffold, an amide 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.
CATO manufactures 8-Chloro-1,3,9-trimethyl-1H-purine-2,6(3H,9H)-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.
