Used primarily in the pharmaceutical industry as an intermediate in the synthesis of antibiotics, particularly beta-lactam antibiotics like amoxicillin. It plays a crucial role in the production of chiral compounds due to its stereospecific properties, ensuring the desired enantiomeric purity in final drug products. Additionally, it is utilized in organic synthesis for constructing complex molecules, particularly in the development of biologically active compounds. Its application extends to research and development laboratories where it serves as a building block for creating novel therapeutic agents.
