CATO supplies 3-Hydroxy-<SC>DL</SC>-kynurenine-(butyric-1,2-<SUP>13</SUP>C<SUB>2</SUB>) dihydrobromide (CAS 1313734-57-4), a certified reference material (molecular formula C8[13C]2H18N2O4, MW 232.25 g/mol) for analytical method development and quality control.
3-Hydroxy-<SC>DL</SC>-kynurenine-(butyric-1,2-<SUP>13</SUP>C<SUB>2</SUB>) dihydrobromide (C8[13C]2H18N2O4) contains an amino-acid-derived structure, an amide 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 3-Hydroxy-<SC>DL</SC>-kynurenine-(butyric-1,2-<SUP>13</SUP>C<SUB>2</SUB>) dihydrobromide 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.
