Drug Information
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. (From Grant and Hackh's Chemical Dictionary, 5th ed, p301, p499) (See all compounds classified as Indicators and Reagents.)|Substances that inhibit or prevent the proliferation of NEOPLASMS. (See all compounds classified as Antineoplastic Agents.)

Tetraphenylphosphonium chloride Use and Manufacturing
Tetraphenylphosphonium chloride is used to generate lipophilic salts from inorganic and organometallic anions. Thus, Ph4P+ is useful as a phase-transfer catalyst, again because it allows inorganic anions to dissolve in organic solvents. Depending on the size of the alkyl groups, the reaction of tetraphenylphosphonium chloride with a lithium dialkylamide can proceed in two directions to give 9-phenyl-9-phosphafluorene and benzene, or triphenylphosphine and the dialkylaniline. Lithium monoalkylamides react with tetraphenylphosphonium chloride to give (also depending on the size of the substituents) either N-alkyltriphenylphosphines or phosphine.
