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.
CATO supplies 2,2,6-Trimethyl-2H-pyrano[3,2-c]quinolin-5(6H)-one (CAS 50333-13-6), a certified reference material (molecular formula C15H15NO2, MW 241.29 g/mol) for analytical method development and quality control.
2,2,6-Trimethyl-2H-pyrano[3,2-c]quinolin-5(6H)-one (C15H15NO2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. Its high carbon-to-hydrogen ratio confers good lipid solubility, 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.
