Chemical Structure

7-Methyl-3H-pyrano[3,2-f]quinolin-8(7H)-one CAS 314770-62-2 chemical structure

Description

7-Methyl-3H-pyrano[3,2-f]quinolin-8(7H)-one (C13H11NO2) 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).

7-Methyl-3H-pyrano[3,2-f]quinolin-8(7H)-one (CAS 314770-62-2) is a high-purity analytical reference standard with the molecular formula C13H11NO2 and a molecular weight of 213.23 g/mol.

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.
