These are aromatic compounds that contain a m-xylene moiety, which is a monocyclic benzene carrying exactly two methyl groups at the 1- and 3-positions. m-Xylene (meta-xylene) is a neutral, aromatic hydrocarbon that is insoluble in water. There are three types of xylene isomers, ortho, meta and para xylene. All xylene isomers are colorless liquids and highly flammable. m-Xylene is a plastic tasting compound. It is naturally found in a number of fruits and nuts including apricots, kiwi fruit, safflower, black walnuts and parsley. Xylenes are not acutely toxic, for example the LD50 (rat, oral) is 4300 mg/kg. Petroleum or gasoline contains about 1 weight percent xylenes. The major use of meta-xylene is in the production of isophthalic acid, which is used as a copolymerizing monomer to alter the properties of polyethylene terephthalate. 1,3-dimethylbenzene (m-xylene) 1,3-Dimethylbenzene, benzylated 1,3-Dimethylbenzol 1,3-Xylene 2, 4-Xylene 2,4-Xylene 3-xylene Benzene, 1, 3-dimethyl- Benzene, 1,3-dimethyl- Benzene, 1,3-dimethyl-, benzylated Benzene, m-dimethyl- BENZENE,1,3-DIMETHYL Benzylated m-xylene Dilan HYDRANAL-Water Standard 0.10 HYDRANAL(R)-Water Standard 0.10 M-dimethylbenzene M-methyltoluene M-xylene M-xylene [un1307] [flammable Liquid] M-xylene, benzylated M-xylenes M-xylol Meta-xylene Santosol 150 Xylene, m- Xylene, mixed isomers C8H10 106.165 106.07825032 1,3-xylene M-xylene 108-38-3 CC1=CC(C)=CC=C1 InChI=1S/C8H10/c1-7-4-3-5-8(2)6-7/h3-6H,1-2H3 IVSZLXZYQVIEFR-UHFFFAOYSA-N belongs to the class of organic compounds known as m-xylenes.
