Description
- General description: 4-Chloro-7-nitrobenzofurazan (NBD-Cl) is a highly sensitive chromogenic and fluorogenic reagent.[1] It is reported to react spontaneously with trans-1-methoxy-3-(trimethylsilyloxy)-1,3-butadiene (Danishefsky′s diene), to afford regioselectively the silyl enol ether, via normal electron-demand Diels-Alder (NEDDA) reaction.[1] A study of the molecular structure, vibrational spectra and NBO (Natural Bond Orbital) analysis of NBD–Cl has been undertaken.[2] Its utility as a pre-column derivatization agent has been examined.[3][4]
- Application: 4-Chloro-7-nitrobenzofurazan (NBD-chloride) was used in the following studies:Synthesis of fluorescent phospholipid-derivative, NBD-didecanoylphosphatidylethanolamine[5]Synthesis of functionalized hydroxynaphthofurazan.[6]Spectrophotometric and spectrofluorometric determination of clemastine hydrogen fumarate, loratadine, losartan potassium and ramipril in pharmaceutical formulations.[1]Synthesis of 7-nitrobenzofurazan (NBD)-labeled maleimide, via Diels-Alder reaction.[7]
