In this test, known as Rothera's test, methyl ketones ( CH 3 C ( = O )-) under alkaline conditions give bright red coloration ( see also iodoform test ).

This reaction forms the basis of the iodoform test which was commonly used in history as a chemical test to determine the presence of a methyl ketone, or a secondary alcohol oxidizable to a methyl ketone.

He provided expert services to a Royal Society and Board of Longitude initiative to improve the optical qualities of glass; He discovered iodoform but did not publish, that honour falling to Georges-Simon Serullas.

In 1822, Serullas added potassium metal to a solution of iodine in ethanol and water to form potassium formate and iodoform, called in the language of that time " hydroiodide of carbon ", and used as an antiseptic.

In its original version, it was a solution of iodoform, turpentine and the solids of Friar's Balsam, that hardened as a dressing to give anaesthetic and antiseptic benefits for wounds that were situated in potentially contaminated areas of the body.

One of the more well-known uses of organoiodine compounds is the so-called iodoform test, where iodoform ( CHI 3 ) is produced by the exhaustive iodination of a methyl ketone ( or another compound capable of being oxidised to a methyl ketone ), as follows:
