¨ The Beillstein test is used for the detection of halogens (chlorine, bromine, or iodine) in an organic compound. The test involves heating the compound with copper wire in a flame, which causes the halogens to react with the copper to form a colored flame. The color of the flame indicates the presence of specific halogens.
