Aspartic acid-beta-p-nitroanilide

Aspartic acid-beta-p-nitroanilide, also known as Aspartyl-p-nitroanilide or Aspartic acid-?-(4-nitroanilide), is a chemical compound used in biochemical and enzymatic assays. It is commonly employed as a substrate for various enzymes, particularly proteases and amidases, in biochemical research and diagnostics. When cleaved by these enzymes, it produces a p-nitroaniline product, which can be quantified spectrophotometrically due to its characteristic absorbance at a specific wavelength.
