As a leading manufacturer and supplier, we aim to clarify the chemistry, synthesis, and specifications of Z-Pro-Pro-OH, ensuring you can confidently buy Z-Pro-Pro-OH for your critical applications.

Chemical Identity and Properties of Z-Pro-Pro-OH

Z-Pro-Pro-OH, also referred to as carbobenzoxy-L-prolyl-L-proline, is a dipeptide formed by linking two L-proline amino acids. Its chemical structure is defined by the CAS Number 7360-23-8. The molecular formula is C18H22N2O5, resulting in a molecular weight of approximately 346.38 g/mol. The defining feature of Z-Pro-Pro-OH is the carbobenzoxy (Z) protecting group attached to the N-terminus of the first proline residue. This protecting group is crucial for peptide synthesis as it selectively blocks the amine functionality, preventing unwanted reactions during coupling steps. The presence of proline residues also contributes to unique conformational preferences within the peptide chain.

Synthesis of Z-Pro-Pro-OH

The synthesis of Z-Pro-Pro-OH typically involves established peptide coupling methodologies. Common approaches include:

  • Solid-Phase Peptide Synthesis (SPPS): This method involves attaching the carboxy-terminal proline to a solid resin support, followed by deprotection of its amino group and coupling with N-Z-protected proline. This process is repeated step-by-step to build the peptide chain.
  • Solution-Phase Synthesis: In this method, protected amino acids are coupled in solution. Activation of N-Z-proline, often using coupling reagents like DCC/HOBt or EDC, followed by reaction with proline, yields the desired dipeptide. This approach is often preferred for larger scale production and offers direct purification of intermediates.
