The molecular framework of (2E)-3-(2-FLUOROPHENYL)-2-PROPENOIC ACID (2E)-3-(2-FLUOROPHENYL)ACRYLIC ACID (2E)-3-(2-FLUOROPHENYL)PROP-2-ENOIC ACID 2-Fluorocinnamic acid 2-PROPENOIC ACID, 3-(2-FLUOROPHENYL)- 2-PROPENOIC ACID, 3-(2-FLUOROPHENYL)-, (2E)- 3-(2-FLUORO-PHENYL)-ACRYLIC ACID 3-(2-FLUOROPHENYL)-2-PROPENOIC ACID 3-(2-FLUOROPHENYL)PROP-2-ENOIC ACID 451-69-4 AS01282 O-FLUOROCINNAMIC ACID OTAVA-BB 7020400348 RARECHEM BK HC T305 TRANS-2-FLUOROCINNAMIC ACID (C9H13FO2) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution. 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
