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 (R)-2-Amino-7-(1,2-dihydroxyethyl)-6-(methylthio)thieno[3,2-g]pteridin-4(9H)-one (CAS 19295-31-9), a certified reference material (molecular formula C11H11N5O3S2, MW 325.37 g/mol) for analytical method development and quality control.
(R)-2-Amino-7-(1,2-dihydroxyethyl)-6-(methylthio)thieno[3,2-g]pteridin-4(9H)-one (C11H11N5O3S2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. It is notably hygroscopic, 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).
As a certified reference material (CRM), (R)-2-Amino-7-(1,2-dihydroxyethyl)-6-(methylthio)thieno[3,2-g]pteridin-4(9H)-one meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
