CATO supplies 7-(3-bromo-4-methoxybenzyl)-1-ethyl-8-(((1R,2R)-2-hydroxycyclopentyl)amino)-3-(2-hydroxyethyl)-3,7-dihydro-1H-purine-2,6-dione (CAS 569351-91-3), a certified reference material (molecular formula C22H28BrN5O5, MW 522.39 g/mol) for analytical method development and quality control.
7-(3-bromo-4-methoxybenzyl)-1-ethyl-8-(((1R,2R)-2-hydroxycyclopentyl)amino)-3-(2-hydroxyethyl)-3,7-dihydro-1H-purine-2,6-dione (C22H28BrN5O5) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage, bromine 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
