Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 5-Amino-N-(3-methoxyphenyl)-1-(2-methylbenzyl)-1H-1,2,3-triazole-4-carboxamide.
5-Amino-N-(3-methoxyphenyl)-1-(2-methylbenzyl)-1H-1,2,3-triazole-4-carboxamide (CAS 899738-01-3) is a high-purity analytical reference standard with the molecular formula C18H19N5O2 and a molecular weight of 337.38 g/mol.
5-Amino-N-(3-methoxyphenyl)-1-(2-methylbenzyl)-1H-1,2,3-triazole-4-carboxamide (C18H19N5O2) contains a steroid core, 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.
