Description

o-Xylene CAS NO 95-47-6 is a high-purity aromatic hydrocarbon isomer, widely recognized as a critical intermediate and solvent in industrial chemistry. Its primary value lies in its excellent solvent properties and its role as a precursor in the synthesis of phthalic anhydride, a key building block for plastics and resins. This product is essential for manufacturers in the chemical synthesis, polymer, paint, and coating industries seeking a reliable and consistent raw material.

Application

• Primary raw material for the production of phthalic anhydride, used in plasticizers (e.g., for PVC) and unsaturated polyester resins.
• High-performance solvent for paints, coatings, inks, and adhesives, offering strong dissolving power.
• Chemical intermediate in the synthesis of dyes, pharmaceuticals, and agrochemicals.
• Component in aviation and motor fuels to improve octane ratings.
• Used in the purification and extraction processes within the petrochemical industry.
• Starting material for the manufacture of isophthalic and terephthalic acids.
• Laboratory reagent for analytical chemistry and research applications.
