General description
Nα-(2,4-二硝基-5-氟苯基)-L-丙氨酰胺（FDAA）是一种手性衍生剂（CDA），与其他CDA相比具有高对映选择性和低灵敏度。它常被用于指定痕量氨基酸的立体化学。
Application
在一项使用反相高效液相色谱-电喷雾电离质谱（RPHPLC-ESI-MS）了解罕见氨基酸的研究中，FDAA被用作衍生化试剂。

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

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
