Chemical Structure
Description
The molecular framework of Ethyl (5-oxo-1-(pyridin-2-yl)-2,5-dihydro-1H-1,2,4-triazol-3-yl)carbamate (C10H11N5O3) is characterized by an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
CATO supplies Ethyl (5-oxo-1-(pyridin-2-yl)-2,5-dihydro-1H-1,2,4-triazol-3-yl)carbamate (CAS 67176-04-9), a certified reference material (molecular formula C10H11N5O3, MW 249.23 g/mol) for analytical method development and quality control.
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.
