The Advantages of High-Purity Chloroauric Acid

Choosing a rigorously refined gold precursor delivers measurable advantages at every stage of your workflow.

High Gold Content & Chemical Purity
PURE's HAuCl₄ is manufactured to maximize gold content while minimizing trace metallic and chemical impurities — delivering a precursor you can rely on from lot to lot.

Excellent Water Solubility
HAuCl₄ dissolves readily in water and polar solvents, making it immediately compatible with chemical reduction processes, electroplating baths, and catalyst preparation workflows without additional dissolution steps.

Stable, Versatile Precursor
Chloroauric acid serves as a chemically stable starting point for an exceptionally wide range of gold-based synthesis routes — from nanoparticle production to supported catalyst preparation to gold thin-film deposition.

Scalable from Lab to Production
Available in quantities and purity grades that scale with your needs, PURE's HAuCl₄ is equally suited to small-scale research synthesis and high-volume industrial manufacturing.

Compliance with Demanding Standards
Ultra-high purity grades support compliance with the stringent quality requirements of semiconductor, pharmaceutical, aerospace, and medical device manufacturing environments.
