Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2-(3-Methyl-7-oxo-3,7-dihydro-6H-[1,2,3]triazolo[4,5-d]pyrimidin-6-yl)-N-(5-methylisoxazol-3-yl)acetamide.

2-(3-Methyl-7-oxo-3,7-dihydro-6H-[1,2,3]triazolo[4,5-d]pyrimidin-6-yl)-N-(5-methylisoxazol-3-yl)acetamide (CAS 946306-80-5), molecular formula C11H11N7O3 and molecular weight 289.25 g/mol, is a CATO reference standard with documented purity and traceability.

2-(3-Methyl-7-oxo-3,7-dihydro-6H-[1,2,3]triazolo[4,5-d]pyrimidin-6-yl)-N-(5-methylisoxazol-3-yl)acetamide (C11H11N7O3) 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), 2-(3-Methyl-7-oxo-3,7-dihydro-6H-[1,2,3]triazolo[4,5-d]pyrimidin-6-yl)-N-(5-methylisoxazol-3-yl)acetamide 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.
