MSE PRO™ cis-1-Boc-4-Amino-L-proline, ≥98.0% Purity

MSE PRO™ cis-1-Boc-4-Amino-L-proline is a proline derivative that offers exceptional value in organic synthesis and medicinal chemistry applications. As a cis-substituted pyrrolidine, it possesses a unique rigid ring structure that can impart conformational constraints and influence the biological activity of target molecules. The strategic incorporation of the tert-butyloxycarbonyl (Boc) protecting group allows for selective deprotection, revealing a reactive primary amine functionality for further derivatization.
