Dimethyl (S)-(-)-Methylsuccinate is widely used as a chiral building block in organic synthesis, particularly in the production of pharmaceuticals. Its enantiopure nature makes it valuable for synthesizing optically active compounds, which are essential in drug development. It is also employed in the preparation of fine chemicals and specialty materials, where its specific stereochemistry plays a critical role. Additionally, it serves as an intermediate in the synthesis of agrochemicals and other biologically active molecules, contributing to the development of more efficient and targeted products.
