Overview

1,4-Diethylbenzene (CAS 105-05-5) is an aromatic hydrocarbon featuring two ethyl substituents positioned para to each other on the benzene ring. This symmetrical disubstituted benzene derivative belongs to the family of alkylbenzenes, which are important industrial intermediates and solvents in chemical manufacturing. With the molecular formula C10H14 and a molecular weight of 134.22 g/mol, 1,4-diethylbenzene exhibits typical aromatic compound characteristics while maintaining distinct properties due to its specific substitution pattern. The compound is classified under ADR Class 3 as a flammable liquid, requiring appropriate handling and storage protocols in industrial environments. The para-diethyl substitution pattern provides 1,4-diethylbenzene with enhanced stability compared to ortho-substituted isomers, making it particularly valuable in applications requiring thermal resistance. This structural configuration also influences its solubility characteristics and chemical reactivity, distinguishing it from other alkylbenzene derivatives. Like other compounds in this chemical family, including substances such as 2-ethylbutyl acetate, it finds applications in specialized industrial processes where specific molecular geometry is crucial. Primary industrial applications include its use as an intermediate in the synthesis of polymers and specialty chemicals, particularly in the production of engineering plastics and high-performance materials. The compound also serves as a solvent in certain chemical processes and as a starting material for the manufacture of more complex aromatic compounds. Its stability and well-defined structure make it suitable for research and development applications in pharmaceutical and agrochemical industries. OYSI provides 1,4-diethylbenzene to European industrial customers, ensuring reliable supply chains for chemical manufacturers and research institutions requiring this specialized aromatic intermediate.
