| | Tetraoctylammonium bromide Usage And Synthesis |
| 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. | | Flammability and Explosibility | Not classified | | Synthesis | Tetra-n-octylammonium bromide can be prepared by reacting 1-bromobutane and tri-n-butylamine in acetonitrile solvent. |
