Chemical Structure
Description
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.
2-((6,7-Dimethoxy-3,4-dihydroisoquinolin-2(1H)-yl)methyl)-5-hydroxy-4H-pyran-4-one (CAS 1190285-68-7), molecular formula C17H19NO5 and molecular weight 317.34 g/mol, is a CATO reference standard with documented purity and traceability.
2-((6,7-Dimethoxy-3,4-dihydroisoquinolin-2(1H)-yl)methyl)-5-hydroxy-4H-pyran-4-one (C17H19NO5) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage. 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.
