For businesses in the chemical and materials science sectors, sourcing high-quality Gold(III) Chloride Trihydrate (CAS 16961-25-4) is paramount for success in applications ranging from catalysis to nanotechnology. As a leading manufacturer and supplier based in China, we understand the critical importance of purity, consistency, and reliable supply chains for our B2B clients. This guide aims to equip procurement managers and R&D scientists with the knowledge to make informed purchasing decisions.

Understanding Gold(III) Chloride Trihydrate (CAS 16961-25-4)
Gold(III) Chloride Trihydrate, also known as chloroauric acid trihydrate, is a critical compound characterized by its golden yellow to yellow-red crystalline appearance. Its molecular formula is AuCl4H7O3, with a molecular weight of 393.83 g/mol. Typically, it is specified with an Au content of ≥50% and a purity of ≥99.9%. It exhibits good solubility in water and ethanol, though it is sensitive to heat and hygroscopic. Its primary uses include acting as a catalyst in organic synthesis, a precursor for gold nanoparticle synthesis, and in trace analytical methods for elements like rubidium and cesium.

Key Considerations When Buying Gold(III) Chloride Trihydrate
When looking to purchase this specialty chemical, several factors should be prioritized:

  • Purity and Assay: Ensure the product meets your required specifications, especially for trace metal analysis or sensitive catalytic reactions. Purity levels of ≥99.9% and specific Au content are common requirements. Always request a Certificate of Analysis (COA) from your supplier.
  • Supplier Reliability and Origin: Partnering with a reputable manufacturer or supplier, particularly one based in China with proven export capabilities, can ensure consistent quality and competitive pricing. Look for suppliers with robust quality control systems.
  • Packaging and Storage: Gold(III) Chloride Trihydrate is typically supplied in glass bottles to maintain its integrity. Proper storage conditions (cool, dry, away from direct sunlight) are crucial to prevent decomposition and deliquescence.
  • Technical Support and Documentation: A good supplier will provide essential technical documents such as Safety Data Sheets (SDS), Technical Data Sheets (TDS), and Certificates of Origin (COO). Prompt customer service and technical support are also indicators of a reliable partner.
