Used primarily as an intermediate in organic synthesis, particularly in the production of pharmaceuticals and fine chemicals. Its structure allows for functionalization at multiple sites, making it valuable in building complex molecules. Commonly employed in the development of active pharmaceutical ingredients (APIs), especially in the synthesis of analgesics and anti-inflammatory agents. Also utilized in the preparation of chiral building blocks for asymmetric synthesis. Its hydroxyl groups enable esterification and etherification reactions, useful in prodrug design and polymer chemistry.
