Xylene 48 (organic compound)

Xylene,with the chemical formula C8H10,is a mixture of xylene or aromatic hydrocarbons composed of two methyl groups at different positions on the benzene ring.There are three isomers:ortho xylene(CAS number 95-47-6),meta xylene(CAS number 108-38-3),and para xylene(CAS number 106-42-3).The three isomers of xylene have the molecular formula C8H10,or are represented by the semi-structured formula C6H4(CH3)2.In industry,xylene refers to a mixture of the above isomers.
