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

The present paper describes an updated knowledge and status on Marfey's reagent (MR), 1-fluoro-2,4-dinitrophenyl-5-L-alanine amide (FDNP-L-Ala-NH(2)). The reagent is used for pre-column derivatization of amino acids followed by HPLC separation of the diastereomers so formed. Emphasis is put on the

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
