Chemical Structure
Description
Owing to a flavonoid core, an amide group, a hydroxyl group, an ether linkage, 1-(Pyrimidin-2-yl)-3a',4',8',8a'-tetrahydrospiro[piperidine-4,6'-[1,3]dioxepino[5,6-d]isoxazole]-3'-carbohydrazide is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 348.36 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
CATO supplies 1-(Pyrimidin-2-yl)-3a',4',8',8a'-tetrahydrospiro[piperidine-4,6'-[1,3]dioxepino[5,6-d]isoxazole]-3'-carbohydrazide (CAS 303153-00-6), a certified reference material (molecular formula C15H20N6O4, MW 348.36 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.
