1-fluoro-2,4-dinitrobenzene
1-fluoro-2,4-dinitrobenzene[¦wən ¦flu̇r·ō ¦tü ¦fȯr dī‚nī·trō′ben‚zēn] (organic chemistry) (NO2)2C6H3F Crystals that are soluble in benzene, propylene glycol, and ether; used as a reagent for labeling terminal amino acid groups and in the detection of phenols. Also known as Sanger's reagent. 1-fluoro-2,4-dinitrobenzene
1-fluor·o-2,4-di·ni·tro·ben·zene (FDNB), (flōr'ō-dī-nī'trō-ben'zēn), A reagent used to combine with the free amino groups of aminoacyl residues in a peptide, thus marking those residues; the combined forms are known as DNP-proteins, Dnp-aminoacyl amino acids, the fluorine having been replaced to leave a dinitrophenyl residue (DNP, Dnp, or N2Ph-) attached to the NH2 group. Hence, the N-terminal amino acid and lysine side chains will be covalently modified. Synonym(s): Sanger reagent |
