Tetraoctylammonium bromide Chemical Properties,Uses,Production
Chemical Properties
white crystalline powder
Uses
TOAB has been used as recognition element in formulating potentiometric membrane to develop an electronic tongue system for monitoring nitrogen species level in water samples.
Uses
Tetraoctylammonium bromide (TOAB) has been used as a phase transfer agent to transfer gold tetrachloroaurate from aqueous phase to organic phase in a two-phase (organic-aqueous) method of alkanethiol stabilized gold nanoparticle synthesis. It is also used to prepare TOAB-capped gold nanoparticles, which shows well-defined plasmon absorption compared to thiol-capped nanoparticles.
General Description
Tetraoctylammonium bromide is an organic surface coating agent commonly used to control the size and shape during nanoparticle synthesis.
