Mesitylene, 1,3,5-Trimethylbenzene, 98%, 100ml CAS Number: 108-67-8    Molecular Weight: 120.19 Molecular Formula: C9H12 IUPAC Name: 1,3,5-Trimethylbenzene Other Names: sym-Trimethylbenzene Mesitylene or 1,3,5-trimethylbenzene is a derivative of benzene with three methyl substituents symmetrically placed on the ring. Isomeric trimethylbenzenes include 1,2,4-trimethylbenzene (pseudocumene) and 1,2,3-trimethylbenzene (hemimellitene). All three compounds have the formula C6H3(CH3)3, which is commonly abbreviated C6H3Me3. Mesitylene is a colourless liquid with sweet aromatic odor. It is a component of coal tar, which is its traditional source. It is a precursor to diverse fine chemicals. The mesityl group (Mes) is a substituent with the formula C6H2Me3 and is found in various other compounds.In the electronics industry, mesitylene has also been used as a developer for photopatternable silicones due to its solvent properties.1,3,5-Trimethylbenzene is also a major urban volatile organic compound (VOC) which results from combustion. It plays a significant role in aerosol and tropospheric ozone formation as well as other reactions in atmospheric chemistry. The three aromatic hydrogen atoms of mesitylene are in identical chemical shift environments. Therefore, they only give a single peak near 6.8 ppm in the 1H NMR spectrum. For this reason, mesitylene is sometimes used as an internal standart in NMR samples that contain aromatic protons.
