Although triphenylmethane is colorless, it is also able to take on color depending on the environment. It is fluorescent under ultraviolet light, and its absorption and fluorescence emission can be used to measure the purity of the compound. Triphenylmethane can also be formed in a variety of colors and upon exposure to air, it can degrade and polymerize leading to the formation of insoluble fibrous material known as triphenylmethyl polymer.

Triphenylmethane also has a range of interesting physical properties. It has a low boiling point of 78.5°C and a melting point of 88.5°C. Its density of 0.9772 g/cm3 and its refractive index of 1.5055 provide evidence of its non-polar nature. It has a vapor pressure of 11mmHg at 60°C and a viscosity of 5.9 cP.

Triphenylmethane is a versatile compound and its derivatives have been used in a number of applications. For example, triphenylsulfonium chloride is used to prepare 3-aminopropyltrimethoxysilane, a compound used to synthesize organosilicon compounds. Triphenylmethane is also used in the production of dyestuffs, including thionine H, which is used as a fluorescent dye. Triphenylmethane derivatives have also been used in the synthesis of xanthenes, which are used as fluorescent compounds for labeling RNA and DNA.

In conclusion, triphenylmethane is a versatile compound with a wide range of applications. Its fluorescent properties, low boiling point and its derivatives are of particular use in the synthesis of other compounds and in the production of polymers and dyestuffs. It is also relatively inexpensive and easy to produce, making it a useful reagent in the laboratory.
