Used as an intermediate in organic synthesis, particularly in the preparation of pharmaceuticals and functionalized polymers. Its ether-linked benzyl and hydroxyl groups allow for selective protection and deprotection strategies in multi-step synthesis. Commonly employed in the development of prodrugs and biocompatible materials due to its solubility-modifying spacers. Also utilized in the design of surfactants and dendrimers where controlled hydrophilicity and molecular flexibility are required.
