Description

Gold (III) chloride trihydrate is a reducing agent. Gold (III) chromium trihydrate can be used for chemical synthesis of gold nanoparticles (NP) and spirochromene derivatives^[1]^[2].

In Vitro

Gold nanoparticle synthesis method^[1]:
1. Prepare a 2.5 mM HAuCl₄·3H₂O solution by mixing 0.05 g of Gold(III) chloride trihydrate with 50 mL of deionized water.
2. Prepare a 6.6 mM sodium hydroxide (NaOH) solution by mixing 0.0264 g of NaOH with 100 mL of deionized water.
3. Control the pH of 10 mL of HAuCl₄·3H₂O solution by adding NaOH until the pH reaches 6.6. This process heats the solution to 85 °C for 30 minutes under vigorous stirring.
4. Prepare a 5 mM sodium citrate (C6H5Na3O7) solution by mixing 0.073 g of sodium citrate with 50 mL of deionized water.
5. Heat 10 mL of sodium citrate solution to about 85°C for about 20 minutes and add HAuCl₄·3H₂O solution after vigorous stirring to obtain a deep red gold nanoparticle solution.
