Soluble in dioxane, ethanol, water, ether and benzene.


Triphenylmethanol is used as a reagent in the research laboratory. It acts as an intermediate in the production of the commercially useful triarylmethane dyes. It is used in the preparation of triphenylmethane. It is also used as an antiproliferative agent. Further, it is used in the preparation of two-electron reduction product of pyrylogen. In addition to this, it reacts with triphenylphosphine oxide to form a 1:1 molecular complex. It serves as a specific clathrate host for methanol and dimethyl sulphoxide and forms clathrate inclusion complexes.


Incompatible with acids, acid chlorides, acid anhydrides and oxidizing agents.

Protection of thiols, such as cysteine residues in peptide synthesis, as their S-trityl derivatives can be accomplished in high yield in TFA. Cleavage can be effected with HBr in AcOH: J. Chem. Soc. (C), 2683 (1970), with Hg(II) salts, or by oxidation to the disulfide with I2 in MeOH: Helv. Chim. Acta, 51, 2061 (1968). See also Appendix 6.
