Analysis Note The xylene isomers are precursors to many chemicals:
• o-xylene is a precursor for phthalic anhydride
• m-xylene is a precursor for isophthalic acid
• p-xylene is a precursor for terephthalic acid and dimethyl terephthalate

The cresol (methylphenol) isomers are also precursors to many chemicals. This chromatogram of a mix of aromatic and methylphenol compounds was generated using an SLB-IL60 ionic liquid column. Its interaction mechanisms allow the separation of all three xylene isomers, and all three cresol isomers.
