Used as an intermediate in organic synthesis, particularly in the preparation of pharmaceuticals and fine chemicals. Its structure, featuring two phenyl groups and a hydroxyl functionality, makes it valuable in building complex molecules where aromatic and alcohol moieties are needed. Commonly employed in the development of active pharmaceutical ingredients (APIs), especially in antihistamines and anticholinergic agents. Also utilized in the synthesis of fragrances and specialty polymers due to its stability and reactivity profile.
