Used in biochemical research as a substrate analog for studying enzyme mechanisms, particularly in proteases and peptidases. Serves as an intermediate in the synthesis of biologically active compounds, including inhibitors of arginine-specific enzymes. Applied in cell culture media formulations to support the growth of certain auxotrophic cell lines. Also utilized in assays involving amino acid transport and metabolism due to its structural similarity to natural amino acids. Stable under standard storage conditions, making it suitable for long-term experimental use.
