Benzene

Benzene (CAS 71-43-2) is a foundational aromatic hydrocarbon used as a chemical intermediate and solvent across petrochemical and industrial manufacturing. It serves as a primary building block for producing a broad range of downstream chemicals at industrial scale. The largest commercial use of benzene is in the production of ethylbenzene, cumene, and cyclohexane. These intermediates feed into styrene, phenol, and nylon supply chains respectively, supporting global manufacturing sectors.

In the pharmaceutical sector, it functions as a process solvent and precursor in the synthesis of active ingredients and fine chemicals. Dye and pigment manufacturers rely on benzene-derived intermediates to produce colorants. These colorants are used extensively in printing inks and packaging materials. It also underpins the production of detergent alkylates and rubber processing chemicals used across personal care and industrial formulations.

Benzene is supplied as a liquid in bulk quantities, typically via tanker or ISO container for large-volume industrial buyers. Standard commercial grades include technical-grade and nitration-grade for various applications. Purity specifications are commonly at 99.9% or higher to meet rigorous industrial requirements. Procurement is generally handled through petrochemical distributors or direct refinery supply agreements given the volume requirements.
