acids
.
In
Aluminum Corporation of America, who pioneered the use of this technique in the late 1920s and early 1930s.[2][3]
In
ferric chloride, used to detect alkaloids. Keller's reagent can also be used to detect other kinds of alkaloids via reactions in which it produces products with a wide range of colors.[4][5][6] Cohn describes its use to detect the principal components of digitalis.[7] The reaction with this reagent is also known as the Keller–Kiliani reaction, after C. C. Keller and H. Kiliani, who both used it to study digitalis in the late 19th century.[8][9]
