76877-33-3 DS09NL006S N-(4-(7-Diethylamino-4-methylcoumarin-3-yl)phenyl)maleimide 1H-Pyrrole-2,5-dione, 1-(4-(7-(diethylamino)-4-methyl-2-oxo-2H-1-benzopyran-3-yl)phenyl)- Demcpm 7-Diethylamino-3-(4'-maleimidylphenyl)-4-methylcoumarin 3-(4-Maleimidophenyl)-4-methyl-7-(diethylamino)coumarin 3-(4-Maleimidylphenyl)-4-methyl-7-diethylamino coumarin 3-Mmdac UNII-DS09NL006S (CAS 76877-33-3) is a high-purity analytical reference standard with the molecular formula C24H34N2O4 and a molecular weight of 414.54 g/mol.

The molecular framework of 76877-33-3 DS09NL006S N-(4-(7-Diethylamino-4-methylcoumarin-3-yl)phenyl)maleimide 1H-Pyrrole-2,5-dione, 1-(4-(7-(diethylamino)-4-methyl-2-oxo-2H-1-benzopyran-3-yl)phenyl)- Demcpm 7-Diethylamino-3-(4'-maleimidylphenyl)-4-methylcoumarin 3-(4-Maleimidophenyl)-4-methyl-7-(diethylamino)coumarin 3-(4-Maleimidylphenyl)-4-methyl-7-diethylamino coumarin 3-Mmdac UNII-DS09NL006S (C24H34N2O4) is characterized by a flavonoid core, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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.
