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).

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.

Some non-protein alpha-amino acids were derivatized with 1-fluoro-2,4-dinitrophenyl-5-L-alaninamide (Marfey's reagent, MR, FDNP-L-Ala-NH(2),) and four of its structural variants FDNP-L-Phe-NH(2), FDNP-L-Val-NH(2), FDNP-L-Leu-NH(2) and FDNP-L-Pro-NH(2). The resultant diastereomers were separated by normal and reversed phase thin layer chromatography (TLC) and reversed phase

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
