4-Chloro-7-nitrobenzo-2-oxa-1,3-diazole Usage And Synthesis
Chemical Properties yellow to light brown crystalline powder
Uses NBD chloride is nonfluorescent until it reacts with primary or secondary amines to produce a fluorescent product. NBD chloride has been extensively used as a derivatizing reagent for chromatography analysis of amino acids and low molecular weight amines.
Uses A fluorescent reagent
Definition ChEBI: A benzoxadiazole that is 2,1,3-benzoxadiazole which is substituted at position 4 by chlorine and at position 7 by a nitro group.
Purification Methods Wash the solid with H2O, and it recrystallises from aqueous EtOH (1:1) as pale yellow needles. It sublimes in a vacuum [Gosh & Whitehouse Biochem J 108 155 1968, UV, NMR: Bolton et al. J Chem Soc 1004 1966].
