1-Pyrenebutanoic acid hydrazide

1-Pyrenebutanoic acid hydrazide (PBH) is a fluorescent labeling reagent commonly used in biochemistry and molecular biology. Spectral Data: λex 340nm, λem 375nm (MeOH). The hydrazide group reacts with carbonyl groups (like aldehydes or ketones) to form hydrazones. This makes PBH useful for labeling oxidized sugars, glycoproteins, or carbonylated biomolecules. It can be used to modify surfaces (e.g., glass or nanoparticles) for biosensing applications. Also used in the derivatization of proteins, carbohydrates, or lipids that have been oxidized to expose reactive carbonyls. PBH is utilized in developing advanced optical materials, where its fluorescence properties can enhance the detection sensitivity of various biological and chemical systems.
