Mesitylene

Mesitylene CAS:108-67-8 supplier Hangzhou Shitai Biotech,Mesitylene (also known as 1,3,5-trimethylbenzene, C9H12) is an aromatic hydrocarbon derived from three hydrogen symmetrically substituted by three methyl groups on the benzene ring. It can be used as raw material for organic synthesis. It is used to prepare three benzene, formic acid, antioxidant, epoxy resin curing agent, polyester resin stabilizer and alkyd resin plasticizer. 2,4,6- trimethylamine is used to produce reactive brilliant blue, K-3R and other dyes.

    Conclusion  

    In   accordance with enterprise standard

    Mesitylene or 1,3,5-trimethylbenzene is a derivative of benzene with three methyl substituents symmetrically placed on the ring. The other two isomeric trimethylbenzenes are 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.
