Applications

Mesitylene is used to make plastics and dyes. It acts as a solvent, ligand in organometallic chemistry and precursor to 2,4,6-trimethylaniline. It is also used as a developer for photopatternable silicones due to its solvent properties in the electronics industry. It is used as an internal standard in nuclear magnetic resonance (NMR) samples due to the presence of three equivalent protons in it. It is involved in the production of trimesic acid and antioxygen, epoxy firming agent and polyester resin stabilizers. Further, it is used as an additive and component in aviation gasoline blends.

Notes

Incompatible with strong oxidizing agents.
