Descrição geral

1-Fluoro-2,4-dinitrobenzene(FDNB, Sanger′s reagent) is used to identify the amino acid sequence. Thischemical is used to label the free amino groups in proteins and peptides. Itcan also be used to protect the amine group, and for phenol deoxygenation. Additionally,it is a very helpful reagent for nucleophilic substitution reactions tointroduce a chromophore group to amines, phenols, and thiols.

Aplicação

1-Fluoro-2,4-dinitrobenzene is used as a derivatization agent:
  • For aminoglycoside compounds such as amikacine, tobramycine, gentamycine, sisomycine, neamine, neomycine-B and neomycine-C.
1-Fluoro-2,4-dinitrobenzene can also be used:
  • To examine the kinetic analysis and analytical uses of reaction with thiols in the presence of several surfactants.

A rapid and simple method is presented for determining neuro-excitatory nonprotein amino acid 3-N-oxalyl-2,3-diaminopropionic acid (beta-ODAP) and non-protein amino acids in Lathyrus sativus. Seed and foliage extracts of Lathyrus sativus were treated with 1-fluoro-2,4-dinitrobenzene (FDNB) and a reversed-phase high-performance liquid
