Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2-Amino-5-(methoxymethyl)-4h,7h-[1,2,4]triazolo[1,5-a]pyrimidin-7-one.
2-Amino-5-(methoxymethyl)-4h,7h-[1,2,4]triazolo[1,5-a]pyrimidin-7-one (CAS 441746-23-2) is a high-purity analytical reference standard with the molecular formula C7H9N5O2 and a molecular weight of 195.18 g/mol.
2-Amino-5-(methoxymethyl)-4h,7h-[1,2,4]triazolo[1,5-a]pyrimidin-7-one (C7H9N5O2) 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. 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.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
