Chlorodiphenylmethane is an important organic halogen intermediate. It is widely used in pharmaceutical industry for the synthesis of antihistamines, antihypertensive drugs and diphenylmethane derivative APIs. In organic synthesis, it is applied to introduce benzhydryl group for preparing dyes, fragrances and heterocyclic compounds. It also serves as a key raw material for the production of fine chemicals, resin modifiers and chemical analytical reagents.
