Mandelin reagent
With the mandelin reagent , also known as "vanadium sulfuric acid" , after the Russian chemist KF Mandelin, a simple spot analysis is carried out to identify alkaloids and other compounds. The reagent is made up in a ratio of 0.5–1 g of ammonium metavanadate per 100–200 ml of concentrated sulfuric acid . The United States Department of Justice recommends the exact composition of 1 g to 100 ml. It is mainly used for tests for ketamine and 4-methoxyamphetamine , but must be freshly prepared for correct detection.
