  • Applications

    2-Ethyl-p-xylene (CAS 1758-88-9) is used primarily as a chemical intermediate and specialty solvent in industrial manufacturing. It serves as a building block in the synthesis of dyes and pigments, as well as certain resins and other specialty chemicals. As a relatively nonpolar aromatic solvent with moderate solvency, it is employed in coatings, inks, and adhesive formulations. It may also function as a fragrance intermediate or odorant in perfumery, reflecting its aromatic character. In addition, it provides a feedstock for organic synthesis to introduce the ethyl substituent onto a para-substituted xylene framework, subject to local regulations and formulation limits.
