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.
Trifluoromethane and chlorodifluoromethane are both used as refrigerants. Chlorodifluoromethane is a refrigerant HCFC, or hydrochlorofluorocarbon, while fluoroform is an HFC, or hydrofluorocarbon. Fluoroform is not ozone depleting. Chloroform is a common solvent in organic chemistry.
used for puncturing into the spine (or cisterns or fontanelles of a new born) for cerebro-spinal fluid aspiration or for injection drugs, specially anesthetics in spinal blocks, epidurals, etc. Ryle's tube or Nasogastric tube: used for nasogastric suction of ingested toxins (or at times introduction of food or drugs). video link
In chemistry, the haloform reaction (also referred to as the Lieben haloform reaction) is a chemical reaction in which a haloform (CHX 3, where X is a halogen) is produced by the exhaustive halogenation of an acetyl group (R−C(=O)CH 3, where R can be either a hydrogen atom, an alkyl or an aryl group), in the presence of a base.
Sodium hypoiodite is an inorganic chemical used as an oxidant in various organic chemical reactions. It causes iodination of nitrogen atoms, such 1H-benzotriazole to give 1-iodo-1H-benzotriazole and an imine to give the analogous iodoimine. [1] It oxidatively cleaves methyl ketones to give iodoform.

a mineral acid with many industrial uses; commonly used in the laboratory preparation of hydrogen halides Phosphorus pentachloride: one of the most important phosphorus chlorides; a chlorinating reagent. Also used as a dehydrating agent for oximes which turn them into nitriles. Phosphorus tribromide: used for the conversion of alcohols to alkyl ...
Because of its high density, diiodomethane is used in the determination of the density of mineral and other solid samples. It can also be used as an optical contact liquid, in conjunction with the gemmological refractometer, for determining the refractive index of certain gemstones. Diiodomethane is a reagent for installing the CH 2 group.
Prior to the introduction of this chromium-based protocol, olefination reactions generally gave Z alkenes or mixtures of isomers. [1] Similar olefination reactions had been performed using a variety of reagents such as zinc and lead chloride; [5] however, these olefination reactions often lead to the formation of diols—the McMurry reaction—rather than the methylenation or alkylidenation of ...
