Drug Information
Substances that inhibit or prevent the proliferation of NEOPLASMS. (See all compounds classified as Antineoplastic Agents.)|Substances used for the detection, identification, analysis, etc. of chemical, biological, or pathologic processes or conditions. Indicators are substances that change in physical appearance, e.g., color, at or approaching the endpoint of a chemical titration, e.g., on the passage between acidity and alkalinity. Reagents are substances used for the detection or determination of another substance by chemical or microscopical means, especially analysis. Types of reagents are precipitants, solvents, oxidizers, reducers, fluxes, and colorimetric reagents.

Tetraphenylphosphonium bromide Use and Manufacturing
Tetraphenylphosphonium bromide is also known as TPP, TPP-Br, TPPB and TPPBr.Tetraphenylphosphonium bromide is a quaternary phosphonium salt mainly used in pharmaceuticals, as accelarator for fluoroelastomers , adhesion promotor for fluoroelastomers and curative of polyacrylate polymers which extends the shelf life of the compound and decreases the mould fouling. This material is highly soluble in water and slightly soluble in alcohols. Tetraphenylphosphonium bromide is a supporting electrolyte for the electroreduction of buckminsterfullerene. It is used to extract heavy metals from aqueous solution as ion-association complexes. Recently, tetraphenylphosphonium bromide (TPPB) has been used to remove technetium from some radioactive waste streams.
Phosphonium, tetraphenyl-, bromide (1:1): ACTIVE|PMN - indicates a commenced PMN (Pre-Manufacture Notices) substance.
