Mecke reagent

Last updated

The Mecke reagent is used as a simple spot-test to presumptively identify alkaloids as well as other compounds. It is composed of a mixture of selenous acid and concentrated sulfuric acid, [1] which is dripped onto the substance being tested.

Contents

The United States Department of Justice method for producing the reagent is the addition of 100 mL of concentrated (95–98%) sulfuric acid to 1 g of selenous acid. While sale to the general public is legal, it is not recommended as strong corrosives can cause permanent skin and eye damage and require extensive safety ratings. [2]
