Description

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system, 1,6,11(2H)-Naphthacenetrione, 4-((6-deoxy-2,4-di-O-methyl-alpha-L-mannopyranosyl)oxy)-3,4-dihydro-2,5,7-trihydroxy-3,9-dimethoxy-2-methyl- 2,5,7-trihydroxy-4-[(2S,3R,4R,5R,6S)-4-hydroxy-3,5-dimethoxy-6-methyl-tetrahydropyran-2-yl]oxy-3,9-dimethoxy-2-methyl-3,4-dihydrotetracene-1,6,11-trione 54526-94-2 NSC204855 Steffimycin B U 40615 is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 588.56 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).
