Z-Arg-OH

Z-Arg-OH (CAS No.: 56672-63-0, CAT No.: SRCZ-011) is a high-purity N-protected arginine derivative, commonly known as benzyloxycarbonylarginine or Cbz-arginine. This amino acid features the classic benzyloxycarbonyl (Cbz or Z) protecting group on the α-amino group, enabling selective protection during peptide synthesis to facilitate controlled chain elongation and minimize undesirable side reactions.

Supplied as a white to off-white crystalline powder with purity ≥98%, Z-Arg-OH exhibits excellent chemical stability and solubility in polar organic solvents such as DMSO, DMF, and methanol. With a molecular formula of C₁₄H₂₂N₄O₄ and molecular weight of 306.35 g/mol, this compound is well-suited for both manual and automated solid-phase or solution-phase peptide synthesis workflows, supporting applications in pharmaceutical development, biochemical research, and peptide therapeutics.
