Methyltriphenylphosphonium bromide Usage And Synthesis
Chemical Propertieswhite powder
UsesPTC catalyst
UsesMethyltriphenylphosphonium bromide is used for methylenation through the Wittig reaction. It is utilized in the synthesis of an enyne and 9-isopropenyl -phenanthrene by using sodium amide as reagent. It is a lipophilic molecule and used to deliver molecules to specific cell components. Further, it acts as an antineoplastic agent.
UsesMethyltriphenylphosphonium Bromide is a lipophilic molecule with a cation allowing for it to be used to deliver molecules to specific cell components. Also considered an antineoplastic agent.
General DescriptionMethyltriphenylphosphoniumbromide is an organophosphorus compound, with potential use as a precursor and a solvent in organic synthesis.

Mettler-Toledo calibration substance ME 30130598, methyltriphenylphosphoniumbromide is ideal for use in the regular calibration of Mettler-Toledo melting point instrument. Its value is a mean of 6 to 12 iterations with a Mettler-Toledo MP70 Excellence instrument that is calibrated against primary standards. The melting point is validated by Capillary method according to European Pharmacopeia (2.2.14.)
Purification MethodsIf the solid is sticky, wash it with *C6H6 and dry it in a vacuum over P2O5.
