Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1,8-Dimethyl-6-phenyl-3a,4,6,8b-tetrahydro-1H,3H-pyrazolo[4',3':5,6]pyrano[4,3-c]isoxazole.
CATO supplies 1,8-Dimethyl-6-phenyl-3a,4,6,8b-tetrahydro-1H,3H-pyrazolo[4',3':5,6]pyrano[4,3-c]isoxazole (CAS 400075-70-9), a certified reference material (molecular formula C15H17N3O2, MW 271.31 g/mol) for analytical method development and quality control.
1,8-Dimethyl-6-phenyl-3a,4,6,8b-tetrahydro-1H,3H-pyrazolo[4',3':5,6]pyrano[4,3-c]isoxazole (C15H17N3O2) 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.
