m-Xylene (CAS 108-38-3)

m-Xylene, formally known as meta-xylene, is an aromatic hydrocarbon with the chemical formula C8H10. It is one of the three isomeric dimethylbenzenes, distinguished by its two methyl groups attached at the meta positions (1,3) on the benzene ring. This structural configuration confers specific properties to m-xylene, such as its boiling point, solubility, and reactivity, which are distinct from those of its ortho and para isomers. As a clear, colorless liquid, m-Xylene is primarily used in the chemical industry as a solvent and as a precursor in the synthesis of isophthalic acid, an important compound used in the production of high-performance polymers and resins. In research, m-xylene′s non-polar nature and moderate evaporation rate make it a valuable solvent for the purification and processing of organic compounds, particularly in settings where the separation of mixtures via techniques like chromatography is required. The compound′s ability to dissolve a wide range of chemicals without interfering with their chemical properties is crucial for analytical and preparative applications in laboratories. Additionally, m-xylene is often used in the study of hydrocarbon structures and behaviors, providing insights into the interactions and stability of methyl-substituted benzene derivatives under various conditions. This research has implications for understanding and innovating in the fields of materials science, environmental chemistry, and industrial solvent applications, reflecting the compound′s versatile role beyond simple industrial usage.
