1,2,4-Trimethylbenzene, also known as pseudocumene, is an organic compound with the chemical formula CH(CH). Classified as an aromatic hydrocarbon, it is a flammable colorless liquid with a strong odor. It is nearly insoluble in water but soluble in organic solvents. It occurs naturally in coal tar and petroleum (about 3%). It is one of the three isomers of trimethylbenzene.

==History== In 1849, Charles Blachford Mansfield rectified coal tar and identified fractions which he hypothesized to be cumole and cymole. The latter fraction boiled slightly above 170°C and had specific density of 0.857.
