A chemical compound is a chemical substance composed of many identical molecules composed of atoms from more than one element held together by chemical bonds. As the below picture of Benzimidazole and Isoindoline Yellow 2140 diagrams suggests, a molecule consisting of atoms of only one element is therefore not a compound. As the diagram suggests, Benzimidazole is a heterocyclic aromatic organic compound. As per the Benzimidazole figure, this bicyclic compound consists of the fusion of benzene and imidazole. Whereas, Isoindolinone Yellow pigments are used in creating color shades from yellow to brown shades. The Isoindolinone pigments exhibit excellent lightfastness properties, offer good heat stability and chemical inertness, and are suitable for many coating or painting applications.
