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 1,3-Dimethyl-2-oxo-2,3-dihydro-1H-benzo[d]imidazole-5-carboxamide.
1,3-Dimethyl-2-oxo-2,3-dihydro-1H-benzo[d]imidazole-5-carboxamide (CAS 797770-01-5), molecular formula C10H11N3O2 and molecular weight 205.21 g/mol, is a CATO reference standard with documented purity and traceability.
1,3-Dimethyl-2-oxo-2,3-dihydro-1H-benzo[d]imidazole-5-carboxamide (C10H11N3O2) 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.
