What is 3,4,9,10-Perylenetetracarboxylic diimide?
Description
Pigment violet 29 is a perylene-based derivative that has a wide range of coloring applications, including paints, inks, paper, carpets, solar cells, and even drugs. Its more formal name is 3,4,9,10-perylenetetracarboxylic acid diimide.
The color of pigment violet 29 has been variously described as dark red-violet, bordeaux, black, maroon, and purple. In its solid form, its color depends on its particle size, its crystallinity, and, in some cases, the angle at which the viewer observes it.
In recent years, the US Environmental Protection Agency reviewed pigment violet 29 under the 2016 update of the Toxic Substances Control Act. In 2018, the EPA reported that the pigment “does not present an unreasonable risk of injury to human health or the environment under the conditions of use.”? The ruling was based on the compound’s low solubility, vapor pressure, and bioaccumulation potential; and, among other factors, its poor absorption across all routes of exposure.
These findings are disputed by Rep. Frank Pallone (D-NJ), who recently became chair of the House Committee on Energy and Commerce. Pallone contends that the EPA did not consider the environmental hazards of the pigment’s uses by individual companies, and he intends to hold hearings on this and other agency rulings.

The Uses of 3,4,9,10-Perylenetetracarboxylic diimide
Used in chemical research. PTCDI is used extensively as an industrial pigment. It is used as tunable laser dye, light-harvesting material, transistor, molecular switched, solar cell, and optoelectronic device. Planar perylene- and naphthalene-based diimide linkers can be employed to tether the Watson- Crick and the Hoogsteen strands of a DNA triplex, thus providing conjugates capable of targeting singlestranded nucleic acids with the formation of hairpin triplexes.
