Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of peptidomimetics and protease inhibitors. Its protected amine and hydroxyl functional groups allow selective reactions in multi-step organic syntheses. Commonly employed in the preparation of beta-amino alcohols and as a building block for drugs targeting neurological and metabolic disorders. Also utilized in the creation of novel bioactive molecules where steric hindrance from the dimethyl group helps control stereochemistry and improve metabolic stability.
