Ethylbenzene

Ethylbenzene (CAS 100-41-4), commonly abbreviated as EB, is a high-volume aromatic hydrocarbon produced primarily as an intermediate in petrochemical manufacturing. It functions as a solvent and chemical building block across industrial, pharmaceutical, and specialty chemical supply chains. The dominant industrial use is as a precursor in styrene monomer production, where EB undergoes catalytic dehydrogenation. This makes it a critical procurement target for polymer and resin manufacturers seeking reliable raw material streams.

In solvent applications, it is used in coatings, adhesives, and ink formulations where aromatic solvency and controlled evaporation rate are required. Pharmaceutical manufacturers source EB as a process solvent for active ingredient synthesis and purification steps. At trace levels, it also appears in flavor and fragrance compounding, where its characteristic aromatic profile contributes to specific formulation targets. This versatility ensures its presence in diverse chemical manufacturing portfolios globally.

Ethylbenzene is supplied as a clear liquid in bulk tanker, ISO container, and drum formats. Standard commercial grades include technical and high-purity specifications, with purity levels typically ranging from 99% to 99.9%+ for demanding synthesis applications. Buyers in regulated industries may require documentation aligned with pharmaceutical-grade solvent standards such as USP or Ph. Eur. monographs. These quality benchmarks ensure the material meets the rigorous safety and purity requirements of the global market.
