Description

Ethylbenzene CAS NO 100-41-4 is a clear, colorless aromatic hydrocarbon liquid with a characteristic gasoline-like odor. It serves as a fundamental petrochemical intermediate, primarily valued for its role in the large-scale production of styrene, a key monomer for plastics and synthetic rubber. This high-purity chemical is essential for manufacturers in the polymer, resin, and specialty chemical industries seeking a reliable feedstock for downstream synthesis.

Application

• Primary Feedstock for Styrene Production: The predominant industrial use, where it is dehydrogenated to manufacture styrene monomer for polystyrene, ABS, SAN, and synthetic rubbers (SBR).
• Solvent and Diluent: Used as a solvent in coatings, adhesives, and inks, and as a diluent in the formulation of paints and varnishes.
• Chemical Synthesis Intermediate: Employed in the production of acetophenone, ethylbenzene hydroperoxide, and other organic compounds.
• Fuel and Octane Booster: A component in gasoline and aviation fuels to enhance octane ratings and improve combustion performance.
• Laboratory Reagent: Utilized as a standard or reagent in analytical chemistry and research laboratories.

Quality Control

Our Ethylbenzene is produced under stringent quality management systems to ensure batch-to-batch consistency and high purity. Each lot undergoes comprehensive analytical testing, including gas chromatography (GC), to verify identity, assay, and impurity profiles. Certificates of Analysis (COA) detailing all test results are provided and available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from heat, sparks, and open flames. Due to its highly volatile nature, keep containers tightly sealed when not in use. Recommended storage temperature is between 15°C and 25°C. Keep away from strong oxidizing agents.
