Zinc chloride, 1 X 500 g (746355-500G)

Zinc chloride (ZnCl₂) is an inorganic compound that is commonly used as a reagent in chemical synthesis. It is used as a mild Lewis acid catalyst in cycloaddition, substitution, electrophilic aromatic additions, and selective reduction reactions. ZnCl₂ is also a useful starting material for the synthesis of many organozinc reagents via transmetalation reaction. Zinc chloride can be used as:      •A catalyst to synthesize 5-substituted 1H-tetrazoles by [3 + 2] cycloaddition reaction of organic nitriles with sodium azide.       •A reagent to promote the hydrolysis of NaBH₄ for the generation of hydrogen.       •A reagent for the activation of carbon materials.
