General description

Gold(III) chloride trihydrate also known as chloroauric acid or auric chloride comes with orange colored crystals or crystal with chunks having a purity of >=99.9% based on trace metals analysis. Gold(III) chloride is a strong oxidizing agent and it finds applications in catalysis, nanotechnology, electroplating, medicine, surface chemistry, glass coloring etc.

Application

Gold(III) chloride trihydrate is a chemical catalyst, often employed in the synthesis of organic compounds. It is used as a catalyst in oxidation reactions, such as the synthesis of vinyl ethers and esters.[1] Gold(III) chloride trihydrate can be used as a precursor for the synthesis of gold nanoparticles, which find applications in fields such as medicine (for targeted drug delivery and imaging), electronics (for conductive inks and sensors), and optics (for surface-enhanced Raman spectroscopy). [2,3] Gold(III) chloride trihydrate is also used in surface chemistry studies, particularly in the modification of surfaces for specific applications, such as in biosensors and fuel cells.

Features and Benefits

  1. Tested with ICP-Mass for confirming the requirements of purity and trace metal analysis ( =< 1000.0 ppm).
  2. Low insoluble matter (=< 0.1 %) of the product and high purity is very reliable for R&D applications
  3. Gold % is in the range of 48.50 - 50.25 %
