Description and Uses

1. Benzhydrols are industrially important compounds. On oxidation Benzhydrols yields Benzophenone, which are useful synthones for fullerenes, bioactive oxygen heterocycles, dyes and medicines. Various Cr (VI) and other oxidizing agents are used for oxidizing benzhydrol.
2. Benzhydrol is widely used as intermediates in pharmaceuticals (including antihistamines), agrochemicals, perfumes and other organic compounds. It is used as a fixative in the perfume industry. It is involved in polymerization reaction as a terminating group. It is used as precursor to prepare modafinil, benztropine and diphehydramine.
3. Intermediate in the preparation of Modafinil (M482500).
