Used as a chiral building block in organic synthesis, particularly in pharmaceuticals and fine chemicals. Its enantiomeric purity makes it valuable for asymmetric synthesis, where stereochemistry is critical. Commonly employed as an intermediate in the production of active pharmaceutical ingredients (APIs), agrochemicals, and specialty esters. Also finds use as a solvent or derivatizing agent in analytical chemistry due to its biodegradability and low toxicity. Its ester functionality allows for easy incorporation into polymer systems, especially in biocompatible or biodegradable materials.
