Overview
Manganese trifluoride is a fluoride of manganese. Manganese is a naturally occurring metal with the symbol Mn and the atomic number 25. It does not occur naturally in its pure form, but is found in many types of rocks in combination with other substances such as oxygen, sulfur, or chlorine. Manganese occurs naturally in most foods and small amounts are needed to stay healthy, as manganese ions act as cofactors for a number of enzymes. (L228, L229)

Chemistry & industry
Pharmacology
Metabolism/Metabolites
Manganese is absorbed mainly via ingestion, but can also be inhaled. It binds to alpha-2-macroglobulin, albumin, or transferrin in the plasma and is distributed to the brain and all other mammalian tissues, though it tends to accumulate more in the liver, pancreas, and kidney. Manganese is capable of existing in a number of oxidation states and is believed to undergo changes in oxidation state within the body. Manganese oxidation state can influence tissue toxicokinetic behavior, and possibly toxicity. Manganese is excreted primarily in the faeces. (L228)
Uses & manufacturing
UsesUsed as a fluorinating agent of organic compounds; [Merck Index]
General Manufacturing InformationManganese fluoride (MnF3): ACTIVE
Applications
DescriptionThe manganese fluoride, MnF3, is preferably formed by fluorination of manganese(III) iodide. It is a solid, and although its decomposition pressure is lower than 10.1325kPa (0.1 atmosphere) at 600°C, fluorine is still released when heated. It is a strong fluorinating agent, which acts with sulfur, boron, silicon, carbon, phosphorus trichloride and carbon tetrachloride when heated. It is used to fluoride gaseous hydrocarbons.
UsesIt is used as a fluorinating agent, useful for conversion of hydrocarbons into fluorocarbons. It is used in organic synthesis as Lewis acid to prepare a number of organic compounds.
UsesFluorinating agent in organic chemistry.
General DescriptionManganese(III) fluoride (also known as manganese trifluoride), MnF3, is a red/purplish solid useful for converting hydrocarbons into fluorocarbons, that is, it is a fluorination agent. It forms a hydrate and numerous derivatives. MnF3 can be produced by reacting a solution of MnF2 in hydrogen fluoride with fluorine.
