Storage & Sensitivity
Hygroscopic. Ambient temperatures.
Soluble in water and alcohol


Au{C(NHMe) 2 } 2 ]Cl·H 2 O and [Au{C(NHMe) 2 } 2 ]Br·H 2 O were obtained by adding methyl isocyanide and 40% aqueous methylamine successively to aqueous solutions of hydrogen tetrachloroaurate(III) hydrate and hydrogen tetrabromoaurate(III) hydrate, respectively. To analyze the influence of the bromide ions in the synthesis of the gold nanorods Hydrogen tetrabromoaurate(III) hydrate is used. Hydrogen tetrabromoaurate(III) hydrate was used for purification in continuous microfluidic synthesis and functionalization of gold nanorods.


Hygroscopic. Store in cool place. Keep container tightly closed in a dry and well-ventilated place. Store away from strong oxidizing agents.
