Mesitylene (also known as 1,3,5-trimethylbenzene) is a benzene derivative. It is colorless and has an aromatic odor. It is a component of coal tar. It is used as a precursor for many fine chemicals. It is also the precursor for the synthesis of the colorant 2,4,6-trimethylaniline. It is used as a specialty solvent in labs. It can also act as a ligand in organometallic chemistry. It is used as a developer for photopatternable siliconesin electronics and also sometimes used as an internal standard in NMR samples that contain aromatic protons.
