Used as an intermediate in organic synthesis, particularly in the production of esters for fragrances and flavorings. It also serves in the preparation of biodegradable polymers and plasticizers due to its ability to modify polymer chain structure. Its hydroxyl and carboxylic acid groups allow for versatile functionalization, making it useful in developing specialty chemicals for coatings and adhesives. Additionally, it has potential applications in pharmaceuticals as a building block for active ingredients requiring chiral centers.
