Description

The molecular framework of (-)-Chorismic acid (3R-trans)-3-(1-Carboxyvinyloxy)-4-hydroxy-1,5-cyclohexadiene-1-carboxylic acid 1,5-Cyclohexadiene-1-carboxylic acid, 3-[(1-carboxyethenyl)oxy]-4-hydroxy-, (3R,4R)- 1,5-Cyclohexadiene-1-carboxylic acid, 3-[(1-carboxyethenyl)oxy]-4-hydroxy-, (3R-trans)- 1,5-Cyclohexadiene-1-carboxylic acid, 3-[(1-carboxyvinyl)oxy]-4-hydroxy-, (3R-trans)- 617-12-9 Chorismic acid chorismate (C10H10O6) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional 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).
