Ortho-Xylene (o-Xylene)
CAS Number: 95-47-6
Ortho-xylene (o-xylene, ≥99.5%) is a pure aromatic isomer used primarily as a chemical feedstock for phthalic anhydride (PA) production and as a high-purity solvent in coatings and chemical synthesis. Its higher boiling point compared to mixed xylenes makes it preferable in applications requiring controlled evaporation.
