6-(4-叠氮-2-硝基苯胺基)己酸 N-羟基琥珀酰亚胺酯

6-(4-Azido-2-nitrophenylamino)hexanoic acid N-hydroxysuccinimide ester is a photoactive, heterobifunctional cross-linking reagent incorporating an extended spacer. Ordinarily, the initial reaction couples via ester to primary amine by amide bond formation in the pH range of 6.5-8.5. The second bonding, non-specific and rapid, occurs during UV irradiation (250-350 nm) via reactive nitrene.
