TCI C1961 Coronene (purified by sublimation) is a polycyclic aromatic hydrocarbon (PAH) made of six benzene rings arranged around one central ring. This arrangement gives a flat, disc-shaped and highly symmetrical molecule. Coronene is often called "superbenzene" and is seen as a small molecular model for graphene. In the laboratory, it is used in organic electronics, photophysics, surface science and astrochemistry research, and as a reference material in PAH studies. It is supplied as a non-heterocyclic building block for researchers who need a well-defined aromatic framework.

Researchers choose coronene for its extended, fully conjugated π-electron system, its flat and rigid shape, and its high symmetry. Together, these properties give it characteristic fluorescence and a strong tendency toward π-π stacking, which makes it useful for studying molecular packing and electronic behaviour. This product is purified by sublimation, a method that removes non-volatile impurities effectively. High purity matters in organic electronics and spectroscopy, where trace impurities can interfere with charge mobility and emission signals and make experimental results harder to interpret.

In Indonesia, coronene is useful for research groups in materials physics, physical chemistry, nanotechnology and environmental science at universities and research institutions. Materials and nanotechnology laboratories can use it as a model compound when studying graphene-like systems and thin organic films. Physical chemistry groups can use it in fluorescence and spectroscopic studies. Environmental science laboratories can use it as a reference compound in PAH-related analytical work, where a well-characterised aromatic standard helps keep comparisons between experiments consistent.
