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).

Separation of amino acid enantiomers and peptide isomers has been made possible through the use of Marfey's reagent and high-performance capillary electrophoresis (HPCE). Samples of amino acids and peptides were first derivatized with Marfey's reagent and subsequently analyzed by HPCE.

Amino acids are quantitatively determined by precolumn derivatization with 1-fluoro-2,4-dinitrophenyl-5-L-alanine amide and reversed-phase high-performance liquid chromatography with photometric detection at 340 nm. Excellent chromatographic resolution of a mixture of the derivatives of 20 amino acids including proline and cystine is

Analytical biochemistry, 202(1), 210-214 (1992-04-01)
A chromatographic assay has been developed to quantitate racemization occurring during attachment of protected amino acids to peptide synthesis resins. Acidolytic cleavage of deprotected amino acids from supports and subsequent derivatization with 1-fluoro-2,4-dinitrophenyl-5-L-alanine amide (Marfey's reagent) gave diastereomers separable by
