Iodoform stored in an ampoule. Iodoform (also known as triiodomethane) is the organoiodine compound with the chemical formula C H I 3.It is a pale yellow, crystalline, volatile substance, with a penetrating and distinctive odor (in older chemistry texts, the smell is sometimes referred to as that of hospitals, where the compound is still commonly used) and, analogous to chloroform, sweetish taste.
Ketones give positive results in Brady's test, the reaction with 2,4-dinitrophenylhydrazine to give the corresponding hydrazone. Ketones may be distinguished from aldehydes by giving a negative result with Tollens' reagent or with Fehling's solution. Methyl ketones give positive results for the iodoform test. [7]
Industrially significant organoiodine compounds, often used as disinfectants or pesticides, are iodoform (CHI 3), methylene iodide (CH 2 I 2), and methyl iodide (CH 3 I). [4] Although methyl iodide is not an industrially important product, it is an important intermediate, being a transiently generated intermediate in the industrial production ...

Hydrazones are a class of organic compounds with the structure R 1 R 2 C=N−NH 2. [1] They are related to ketones and aldehydes by the replacement of the oxygen =O with the = N−NH 2 functional group. They are formed usually by the action of hydrazine on ketones or aldehydes. [2] [3]
