General description
Nα-(2,4-Dinitro-5-fluorophenyl)-L-alaninamide (FDAA) is a chiral derivatizing agent (CDA), has high enantioselectivity but low sensitivity as compared to other CDAs. It is generally used to assign the stereochemistry of amino acids in trace amounts.
Application
FDAA was used as derivatizing reagent, in a study performed to understand unusual amino acids using reversed phase high performance liquid chromatography-electrospray ionization mass spectrometry (RPHPLC-ESI-MS).
Other Notes
Derivatization reagent for the assay of unusual chiral α-amino acid analogs
