Frequently Asked Questions
What is ethylbenzene used for?
Ethylbenzene (CAS 100-41-4) is used predominantly as the feedstock for styrene monomer production and downstream polystyrene. It also serves as a solvent for resins, paints, and coatings, as a blending component in automotive and aviation fuels, and as a chemical intermediate.
What is the common name of ethylbenzene?
Ethylbenzene is generally referred to by that name; it is also known as phenylethane or ethylbenzol. It is an aromatic hydrocarbon, C8H10, CAS 100-41-4.
What products contain ethylbenzene?
Industrially it is the precursor to styrene and polystyrene, and it appears as a solvent in resins, paints, and coatings and as a component of motor and aviation fuels. It is supplied as an industrial feedstock and solvent rather than a finished consumer product.
How is ethylbenzene shipped, and what is its UN number?
Ethylbenzene ships under UN 1175 as a flammable liquid. RawSource supplies it in bulk — drums, totes/IBCs, and larger volumes — with CoA and SDS. Refer to the SDS for full transport and handling classification.
What is the cost of bulk ethylbenzene?
Bulk pricing depends on grade, packaging, and volume and tracks aromatics markets. Submit a bulk RFQ with your specification and quantity for a current quote; we do not list spot prices.
What is the REACH and TSCA regulatory status of Ethylbenzene?
Ethylbenzene (CAS 100-41-4) is subject to U.S. TSCA Inventory requirements; supplying it into the EU requires valid REACH registration ((EC) No 1907/2006). RawSource cannot verify a third-party supplier's registrations — buyers should require documented TSCA and REACH compliance for their jurisdiction and volume (EC 202-849-4).
