Used as a chiral building block in organic synthesis, particularly in the preparation of pharmaceuticals and fine chemicals. Its alkyne functionality allows for coupling reactions, such as Sonogashira or Click chemistry, enabling the construction of complex molecular structures. The hydroxyl group provides a site for further modification, such as esterification or ether formation. Due to its stereochemistry, it is valuable in asymmetric synthesis where control of three-dimensional structure is critical, especially in the development of bioactive molecules.
