General description
Methyltriphenylphosphoniumbromide 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 MP90 Excellence instrument that is calibrated against primary standards. The melting point is validated by Capillary method according to European Pharmacopeia (2.2.14.)
