Aluminium Chloride Anhydrous Extra Pure is a high-purity, white to yellowish crystalline compound that is highly hygroscopic and fuming in moist air. It is extensively used in laboratory chemistry as a powerful Lewis acid catalyst, particularly in Friedel-Crafts alkylation and acylation reactions, as well as in the synthesis of organometallic compounds. Its anhydrous form ensures optimal reactivity and effectiveness in moisture-sensitive processes, including polymerization and halogenation studies. Due to its corrosive nature and tendency to react violently with water, it must be handled in a dry, controlled environment using proper safety measures. This extra pure grade is ideal for high-precision analytical and preparative procedures in organic and inorganic chemistry research.
