Description
The occurrence of 892156-28-4 Ethyl 9-{4-[(2,5-dioxopyrrolidin-1-yl)oxy]-4-oxobutyl}-6,8,8-trimethyl-2-oxo-6,7,8,9-tetrahydro-2H-pyrano[3,2-g]quinoline-3-carboxylate DTXSID10583415 is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 892156-28-4 Ethyl 9-{4-[(2,5-dioxopyrrolidin-1-yl)oxy]-4-oxobutyl}-6,8,8-trimethyl-2-oxo-6,7,8,9-tetrahydro-2H-pyrano[3,2-g]quinoline-3-carboxylate DTXSID10583415 (CAS 892156-28-4), a certified reference material (molecular formula C26H36N2O8, MW 504.57 g/mol) for analytical method development and quality control.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, 892156-28-4 Ethyl 9-{4-[(2,5-dioxopyrrolidin-1-yl)oxy]-4-oxobutyl}-6,8,8-trimethyl-2-oxo-6,7,8,9-tetrahydro-2H-pyrano[3,2-g]quinoline-3-carboxylate DTXSID10583415 is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 504.57 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).
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.
