Product description

Xylene, whose chemical formula is C8H10, is the product of the substitution of two hydrogens on the benzene ring by methyl. There are three isomers, namely, o-xylene (CAS number 95-47-6), m-xylene (CAS number 108-38-3) and p-xylene (CAS number 106-42-3). In industry, xylene refers to a mixture of these isomers.
