Description

L-Aspartic Acid α-(β-Naphthylamide) is a specialized biochemical derivative of aspartic acid, where the α-carboxyl group is linked to a β-naphthylamine moiety. This compound serves as a critical chromogenic substrate for the detection and quantification of proteolytic enzyme activity, particularly in diagnostic and research applications. It is primarily utilized by manufacturers and research institutions in the life sciences, pharmaceutical development, and clinical diagnostics sectors for precise biochemical analysis.

Application

• As a specific chromogenic substrate for the assay of aminopeptidases and other proteolytic enzymes.
• In the development and quality control of diagnostic kits for clinical laboratories.
• For biochemical research involving enzyme kinetics and inhibition studies.
• As a key intermediate in the synthesis of more complex peptidomimetics and research chemicals.
• In academic and industrial settings for high-throughput screening (HTS) assays.
