(R)-1-Phenyl-1,2-ethanediol 2-Tosylate is primarily used in organic synthesis as a chiral building block. It serves as a key intermediate in the preparation of enantiomerically pure compounds, particularly in the pharmaceutical industry. The tosylate group enhances reactivity, making it a valuable precursor for nucleophilic substitution reactions. It is often employed in the synthesis of biologically active molecules, such as drugs and agrochemicals, where stereochemistry plays a critical role in efficacy. Additionally, it is utilized in asymmetric synthesis to create complex chiral structures, contributing to the development of advanced materials and fine chemicals.
