Application

Gold(III) bromide serves as a versatile catalyst in various chemical reactions, primarily due to its catalytic ability to facilitate the formation of six-membered cyclic compounds from enynal units and carbonyl compounds. Additionally, it plays a critical role in the nucleophilic substitution reactions of propargylic alcohols by acting as an alcohol-activating agent. Beyond its catalytic functions, Gold(III) bromide is utilized as a testing reagent for detecting ketamine and is involved in the analysis of alkaloids and spermatic fluid, making it valuable in medical and analytical applications. Despite its practical uses, it is characterized by its yellowish-gray mass, decomposes at approximately 165°C, and remains insoluble in water.
