Triphenylmethane derivatives can be used to prepare high-performance polymers. For example, triphenylmethane diisocyanate (TPMDI) is an important monomer of polyurethane materials, which can improve the heat resistance and mechanical strength of the materials. In addition, it is added to plastics as an antioxidant or stabilizer to extend the service life of the products. In the field of nanotechnology, derivatives of triphenylmethane (such as surface-functionalized triphenylphosphine molecules) are used to design targeted nanomaterials, for example, to achieve precise positioning through surface modification in cancer photothermal therapy.

Triphenylmethane is a low-toxic substance. The oral LD50 value for rats has not been clearly reported, but long-term contact may cause irritation to the skin and mucous membranes. Inhalation of its dust may cause respiratory discomfort, and protective equipment must be worn during operation. When storing, it should be sealed in a cool and dry place, away from open flames and oxidants to prevent combustion or oxidation reactions.
