Used in biochemical research as a chromogenic substrate for detecting β-fucosidase enzyme activity. It serves as a synthetic analog of natural glycosides, allowing scientists to study enzyme kinetics and inhibition in lysosomal storage disorders. Commonly employed in histochemical staining to visualize enzyme distribution in tissues. Also utilized in the development of diagnostic assays for metabolic diseases involving glycosidases. Its aromatic amine group enables easy detection through colorimetric or fluorometric methods after enzymatic cleavage.
