(S)-2-((Methylsulfonyl)oxy)propanoic acid is primarily used as an intermediate in organic synthesis, particularly in the production of pharmaceuticals and fine chemicals. Its chiral structure makes it valuable for the synthesis of enantiomerically pure compounds, which are crucial in drug development to ensure specificity and efficacy. It is often employed in the preparation of active pharmaceutical ingredients (APIs) where stereochemistry plays a critical role in biological activity. Additionally, it can be utilized in the development of agrochemicals and specialty chemicals, where its reactive functional groups enable the creation of complex molecules with tailored properties.
