Used as an intermediate in the synthesis of pharmaceuticals, particularly in the production of muscle relaxants and central nervous system agents. It serves as a building block in organic synthesis due to its two hydroxyl groups, which allow for functionalization and ring formation. Commonly employed in the preparation of benzodiazepine analogs and other bioactive molecules. Also utilized in the development of specialty polymers and resins where controlled hydrophilicity and flexibility are required. Its benzyl group provides stability and influences lipophilicity, making it suitable for drug design with improved membrane permeability.
