"m"-Xylene is an aromatic hydrocarbon, based on benzene with two methyl substituents.

It is an isomer of "o"-xylene and "p"-xylene. The "m" stands for "meta", meaning the two methyl substituents are at locants 1 and 3 on the aromatic ring.

The major chemical use of metaxylene is in the manufacture of isophthalic acid, which is used as a copolymer to alter the properties of Polyethylene terephthalate (PET) making PET more suitable for the manufacture of soft drinks bottles.
