1,2,4-Trimethylbenzene Market Summary

1,2,4-Trimethylbenzene (TMB), commonly known as pseudocumene, is a colorless liquid aromatic compound with the chemical formula C9H12. It is one of three trimethylbenzene isomers and is a crucial specialty intermediate chemical derived primarily from the petrochemical industry. TMB naturally occurs in coal tar and petroleum (constituting about 3% of the latter). Industrially, it is extracted and separated from the C9 aromatic fraction of petroleum refining, where it typically makes up around 40% of that specific cut. TMB is highly flammable, possesses a strong odor, is nearly insoluble in water, but readily dissolves in organic solvents such as ethanol, ether, and benzene.
The market for 1,2,4-Trimethylbenzene is uniquely characterized by its near-total reliance on one downstream product: Trimellitic Anhydride (TMA).
● Single-Product Dependence: Over 90% of the global consumption of TMB is dedicated to the production of TMA, making the TMB market highly sensitive to the economic cycles and technological trends of the TMA industry.
● Gateway to High-End Fine Chemicals: While TMB is an intermediate petrochemical, TMA is a high-end product within the fine chemical sector, valued for imparting superior thermal, electrical, and chemical resistance properties to various materials.
