Product Overview

Aluminium Chloride Anhydrous 98% Extra Pure (CAS No. 7446-70-0) is an anhydrous aluminium halide distinguished by its strong electron-pair-accepting character. Although commonly represented as an inorganic salt, aluminium chloride exhibits substantial covalent character and functions as a powerful Lewis acid by coordinating with electron-rich molecules and activating suitable substrates for chemical transformation. This behaviour gives anhydrous aluminium chloride particular importance in organic synthesis and Lewis-acid-mediated reaction chemistry.

The Extra Pure grade is intended for routine laboratory synthesis, preparative chemistry, reaction development, and research procedures requiring a dependable source of anhydrous aluminium chloride. It is suited to organic and inorganic laboratory work in which the compound is employed as a Lewis acid, reaction promoter, or synthetic reagent, with the suitability and quantity determined by the requirements of the individual procedure.

Typical Applications

• Lewis acid in Friedel–Crafts alkylation reactions
• Promotion of Friedel–Crafts acylation for preparing aromatic ketones
• Activation of acyl halides, alkyl halides, and related electrophilic reagents
• Catalyst or reaction promoter in aromatic halogenation procedures
• Cleavage and transformation of selected aryl ether systems
• Hydrocarbon isomerisation and polymerisation studies
• Preparation of alkylbenzenes and other substituted aromatic intermediates
• Reaction-development and preparative work involving Lewis-acid-mediated transformations

Aluminium chloride is widely established as a Lewis acid for Friedel–Crafts chemistry and is also used in aromatic halogenation, hydrocarbon transformation, and other electrophilic synthetic processes.
