Cbz-S-3-amino-3-phenylpropan-1-ol is primarily used in organic synthesis as a building block for the preparation of more complex molecules. It serves as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of compounds with potential therapeutic effects. The presence of the Cbz (carbobenzyloxy) protecting group allows for selective deprotection, enabling controlled reactions in multi-step synthetic processes. This compound is also utilized in the study of enzyme inhibitors and receptor ligands, contributing to research in medicinal chemistry. Its structure makes it valuable for creating chiral molecules, which are essential in the production of enantiomerically pure drugs.
