Ethylbenzene is an aromatic hydrocarbon (C6H5C2H5) primarily used as a precursor in the production of styrene, a key monomer for polystyrene plastics and synthetic rubber. It also serves as a solvent in industrial processes. This clear, flammable liquid has a CAS number of 100-41-4 and a molecular weight of 106.17 g/mol, requiring ambient storage with proper ventilation. It carries a **Danger** signal word due to its toxicity and flammability. Molekula supplies Ethylbenzene from research to bulk quantities with full documentation and ISO 9001:2015 traceability.
