[Chemical Properties]

white crystalline powder
[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.
[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.
[General Description]

Tetraoctylammonium bromide is an organic surface coating agent commonly used to control the size and shape during nanoparticle synthesis.
