Description

Structurally, J81E81G364 131179-95-8 Efaproxiral [USAN:INN] Efaproxiral Propanoic acid, 2-(4-(2-((3,5-dimethylphenyl)amino)-2-oxoethyl)phenoxy)-2-methyl- 2-(4-(((3,5-Dimethylanilino)carbonyl)methyl)phenoxy)-2-methylpropionic acid 2-Dacmpp RSR 13 Efaproxyn 2-(4-((3,5-Dimethylphenyl)amino)-2-oxoethyl)phenoxy)-2-methylpropanic acid UNII-J81E81G364 RSR13 (C20H23NO4) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 10.0, corresponding to approximately 10 ring(s) or double-bond equivalent(s). With a molecular weight of 341.40 g/mol, it falls into the moderately-high-molecular-weight range. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
