1,2,4-Trimethylbenzene CAS#95-63-6
Also known as pseudocumene, this compound belongs to aromatic hydrocarbons. It is widely found in industrial mixed solvents with corresponding boiling ranges. Among trimethylbenzene isomers, pseudocumene is the most extensively adopted variant for commercial manufacturing and solvent applications. The aromatic fractions within hydrocarbon solvents mainly consist of single-ring alkylated aromatics, as well as double-ring aromatic structures that may carry alkyl substituents. This product features stable dissolving capacity and serves as critical raw material for producing trimellitic anhydride, high-performance industrial solvents, coating formulations and fine chemical intermediates. We can supply cargo with stable quality, and supporting documents including COA and MSDS will be provided upon request.
