Product Overview

Benzene 99% Extra Pure (CAS No. 71-43-2) is the parent monocyclic aromatic hydrocarbon, consisting of a planar six-membered carbon ring with a delocalised π-electron system. This aromatic stabilisation distinguishes benzene from ordinary cyclic polyenes and governs its characteristic preference for substitution reactions that retain the conjugated ring. Its structurally symmetrical aromatic framework makes benzene an important starting substrate and model compound in organic and physical chemistry.

The Extra Pure grade is intended for routine organic synthesis, reaction-development work, solvent-based laboratory procedures, and general research requiring benzene of defined assay. It is suitable for controlled electrophilic aromatic substitution, preparation of substituted benzene intermediates, and investigations of aromatic reactivity, solvent effects, molecular interactions, and related physicochemical behaviour.

Typical Applications

• Starting material for nitration, sulphonation, halogenation, alkylation, and acylation reactions involving the benzene ring.
• Preparation of nitrobenzene, halobenzenes, alkylbenzenes, aryl ketones, and other substituted aromatic intermediates.
• Non-polar reaction or extraction medium in controlled laboratory procedures that specifically prescribe benzene.
• Model aromatic hydrocarbon in reaction-mechanism and electrophilic-substitution studies.
• Investigation of solvent effects, molecular association, solubility, partitioning, and physical-organic behaviour.
• General laboratory research involving aromatic hydrocarbons and conjugated ring systems.

Common Synonyms

• Benzol
• Benzole
• Cyclohexatriene
• [6]Annulene

Storage Conditions

Store in a tightly closed container in a cool, dry, and well-ventilated area. Protect from heat, direct sunlight, ignition sources, evaporation, and contamination. Minimise unnecessary container opening and reseal promptly after use to preserve product concentration and reagent cleanliness.
