The following is the introduction of high quality 1,2,4,5-Tetramethylbenzene CAS 95-93-2, hoping to help you better understand 1,2,4,5-Tetramethylbenzene CAS 95-93-2. Mesitylene, or 1,2,4,5-tetratoluene, is an organic compound with the chemical formula C6H2(CH3)4. It is a colorless solid with a sweet odor. It is one of the three isomers of tetratoluene, the other two being Chemicalbook 1,2,3,4-tetratoluene (melting point −6.2°C) and 1,2,3,5-tetratoluene (melting point − 23.7°C). The high melting point of mesitylene (79.2°C) reflects its high molecular symmetry.
