(Methoxycarbonylmethyl)triphenylphosphonium bromide is a reactant for the synthesis of GSK-3 inhibitors using the Wittig reaction, substituted furanones for antifungal and cytostatic activities, photochromic dithienylethene derivatives, gem-diiodoalkanes containing allylic alcohols and highly substituted cyclopentenes and brazilanes via Au-catalyzed deoxygenative Nazarov cyclization. As reactant for asymmetric hydrogenation of α,β-unsaturated ester-phosphonates, studies of thermal decomposition of phosphonium alkyl ester salts.


Hygroscopic. Store in cool place. Keep container tightly closed in a dry and well-ventilated place. Store away from strong oxidizing agents, water, moisture.
