Applicazioni

Iodoform is use as a disinfectant. It is an active ingredient of ear powder along with other constituents like zinc oxide and propanoic acid, which prevent infection and facilitate the removal of ear hair in dogs and cats. In analytical chemistry, it is involved in the determination of iodoform in drinking water as well as to remove heavy metals like mercury from fluids. It plays an important role in the fermentation of bio mass. It is also used in root canal therapy for infected primary teeth.

Note

Light sensitive. Incompatible with strong bases, alkali metals, trong oxidizing agents and magnesium.
