Mesitylene（Cat No.:R022766）, also known as 1,3,5-trimethylbenzene, is a colorless, flammable liquid aromatic hydrocarbon with three methyl groups symmetrically substituted on a benzene ring. It is widely used as a solvent, intermediate, and raw material in the manufacture of dyes, resins, and pharmaceuticals. Due to its high boiling point and chemical stability, mesitylene is valuable in high-temperature reaction media and as a calibration standard in NMR spectroscopy. Its electron-rich aromatic structure makes it reactive in electrophilic substitution, alkylation, and oxidation reactions, supporting diverse synthetic and industrial applications.
