Description

The molecular framework of 66635-85-6 S9B9E35WUX Anirolac Anirolac [USAN:INN] 1H-Pyrrolizine-1-carboxylic acid, 2,3-dihydro-5-(4-methoxybenzoyl)-, (+-)- Anirolaco [Spanish] Anirolacum [Latin] (+-)-5-p-Anisoyl-2,3-dihydro-1H-pyrrolizine-1-carboxylic acid RS 37326 Anirolaco Anirolacum UNII-S9B9E35WUX RS-37326 (C16H15NO4) 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).
