Zinc Chloride USP
Abstract
Zinc chloride is the name of chemical compounds with the formula ZnCl2 and its hydrates. Zinc chlorides, of which nine crystalline forms are known, are colorless or white, and are highly soluble in water.
Use/Application
Zinc chloride has the ability to react with metal oxides (MO) to give derivatives of the formula MZnOCl2. It finds wide use, principally as a moderate-strength Lewis acid. It can catalyze (A) the Fischer indole synthesis. Zinc chloride finds wide application in the textile processing, metallurgical fluxes, and chemical synthesis.
