General description
Nα-(2,4-Dinitro-5-fluorophenyl)-L-valinamide [L-FDVA] is a derivatizing chiral agent.
Application
L-FDVA may be used as derivatizing agent for amino acids in the isolation and identification of microcystins.
Packaging
Bottomless glass bottle. Contents are inside inserted fused cone.
Other Notes
Chiral derivatizing agent (chiral Sanger′s Reagent) for determining the enantiomeric purity of amino acids with HPLC; This analogue of Marfey′s reagent can also be used with amines
