myo-Inositol hexaacetate serves as a key intermediate in organic synthesis, particularly for protecting the hydroxyl groups of inositol during the preparation of complex derivatives used in pharmaceutical and biochemical research. Its multiple acetyl groups enable precise chemical control and temporary protection of -OH functionalities in the synthesis of cyclic compounds or carbohydrate analogs. Due to its biocompatibility, low water solubility, and slow biodegradability, it is also utilized in biomaterials and explored in drug delivery systems, such as ester-based prodrugs.
