The occurrence of Sodium 5-methyl-2-((3-methyl-2,7-dioxo-2,7-dihydro-3H-naphtho[1,2,3-de]quinolin-6-yl)amino)benzenesulfonate is closely related to a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
Sodium 5-methyl-2-((3-methyl-2,7-dioxo-2,7-dihydro-3H-naphtho[1,2,3-de]quinolin-6-yl)amino)benzenesulfonate (CAS 4478-76-6), molecular formula C24H17N2O5SNa and molecular weight 468.46 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, Sodium 5-methyl-2-((3-methyl-2,7-dioxo-2,7-dihydro-3H-naphtho[1,2,3-de]quinolin-6-yl)amino)benzenesulfonate is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 468.46 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.
