| Hazard Information | Back Directory | [Uses]
Methyltriphenylphosphonium chloride is used as a phase transfer catalyst in synthetic chemistry. It acts as a catalyst for regio-controlled ring-opening polymerization of substituted epoxides. It is utilized for controlling the corrosion iron. It acts as a reactant for intramolecular nitrone cycloaddition. In addition to this, it is used for neoplasm inhibition through antimitochondrial effect. | [reaction suitability]
