Quick Summary

Meta-xylene is one of three isomers of dimethylbenzene, all sharing the chemical formula C6H4(CH3)2 but differing in the arrangement of their methyl groups. Meta-xylene is the most abundant isomer in commercial xylene mixtures, typically making up 50-60%.1

Xylenes are used as solvents, in aviation fuel, and as precursors for dyes, fibers, and films. Meta-xylene can be purified from mixtures and is used in the production of xylidines for dyes and xylene musk for perfumes.1
