Z-Asp-OH

Z-Asp-OH (CAS No.: 1152-61-0, CAT No.: SRCZ-007) is a high-purity N-protected aspartic acid derivative, also known as benzyloxycarbonylaspartic acid or Cbz-aspartic acid. Featuring the classic Cbz (benzyloxycarbonyl, Z) protecting group on the amino terminus, this compound plays a vital role as a building block in advanced peptide synthesis and medicinal chemistry. It enables selective protection of the amine functionality, facilitating precise peptide chain assembly and minimizing side reactions during multi-step synthesis protocols.

Supplied as a white to off-white crystalline powder with excellent purity (≥98%), Z-Asp-OH exhibits strong chemical stability and good solubility in common organic solvents such as DMSO, DMF, and methanol. With a molecular formula of C₁₂H₁₃NO₆ and a molecular weight of 267.24 g/mol, it is well-suited for use in both manual and automated peptide synthesis platforms, and supports scalable research and pharmaceutical development applications.
