Chemical Structure
Description
CATO supplies N-Phenyl-2-{[3-(3-pyridinyl)-4,5-dihydro-5-isoxazolyl]carbonyl}-1-hydrazinecarboxamide (CAS 478064-64-1), a certified reference material (molecular formula C16H15N5O3, MW 325.32 g/mol) for analytical method development and quality control.
N-Phenyl-2-{[3-(3-pyridinyl)-4,5-dihydro-5-isoxazolyl]carbonyl}-1-hydrazinecarboxamide (C16H15N5O3) contains a nitrogen-containing heterocyclic scaffold, 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.
