Peptide synthesis (especially solid-phase peptide synthesis SPPS). Pharmaceutical and biotech research for designing arginine-containing peptides. Used in medicinal chemistry to develop stable peptide analogs.

The Boc group protects the amino group preventing unwanted reactions. Enables controlled step-by-step peptide chain assembly. Allows incorporation of D-arginine to improve stability and biological properties of peptides.

Protected D-arginine derivative with a Boc protecting group. Exists as a hydrochloride salt with water of hydration. Good solubility in water and polar solvents. Used mainly as a synthetic intermediate.
