In the realm of specialized chemicals, Gold Powder (CAS 7440-57-5) represents a material with distinct properties and a range of niche applications. As a fine chemical and a potential pharmaceutical intermediate, its availability and quality are of significant interest to R&D scientists, formulators, and procurement specialists. This article explores the characteristics of Gold Powder and the advantages of sourcing it from China.

Understanding the Chemistry of Gold Powder

Gold, with the symbol Au and CAS number 7440-57-5, is a precious metal known for its inertness and conductivity. When processed into a powder, it retains these fundamental properties while offering increased surface area and unique application potential. The molecular weight of Au is 196.9666, and its density is a notable 19.3 g/mL at 25°C. A key attribute is its solubility, which is effectively zero, meaning it does not readily dissolve in common solvents, ensuring its presence as a distinct component in formulations.

The purity of Gold Powder is a critical factor. High-purity grades, often specified as ≥99%, are essential for applications where precision and absence of contaminants are paramount. This is particularly true when considering its use as a pharmaceutical intermediate, where even minor impurities can affect drug efficacy or safety profiles.

Applications: Beyond Aesthetics

While the visual appeal of gold is undeniable, Gold Powder serves functional purposes in various industries:

  • Pharmaceutical Intermediates: Its catalytic properties or its role in specialized drug delivery systems make it valuable in pharmaceutical synthesis. Companies looking to buy Gold Powder for these purposes must ensure high purity and consistent batch-to-batch quality.
  • Fine Chemical Synthesis: Gold's catalytic capabilities are utilized in various chemical reactions. It can act as a catalyst in organic transformations, aiding in the creation of complex molecules.
  • Advanced Materials: Gold nanoparticles and powders are explored for applications in electronics, sensors, and advanced composites due to their unique optical and electronic properties.
  • Specialty Coatings: In some high-performance coatings, gold powder can be incorporated for its reflective or conductive properties.

When searching for Gold Powder, understanding the intended application is crucial for selecting the correct grade and purity. For example, sourcing Gold Powder for an API intermediate will have different requirements than for a decorative pigment.

Sourcing from China: Advantages for Buyers

The global market for specialized chemicals often includes manufacturers from China, and Gold Powder is no exception. NINGBO INNO PHARMCHEM CO.,LTD., for instance, is a supplier that offers competitive pricing and has established production facilities. The advantages of sourcing Gold Powder from Chinese manufacturers include:

  • Competitive Pricing: Chinese manufacturers often provide cost-effective solutions for bulk chemical purchases, making it attractive for companies aiming to optimize their budget.
  • Large-Scale Production: Many Chinese chemical companies are equipped to handle large production volumes, ensuring a stable supply chain for businesses with high demand.
  • Export Expertise: These suppliers are experienced in international trade, offering various shipping options (Ocean, Land, Air) and payment terms (L/C, T/T, Paypal) to facilitate global transactions.

When engaging with a Chinese Gold Powder supplier, it is recommended to request detailed product specifications, inquire about their quality control processes, and clarify shipping and payment terms. Obtaining a quote and potentially a sample is a standard practice to verify product quality before committing to a purchase.

In summary, Gold Powder (CAS 7440-57-5) is a specialized chemical with significant potential in pharmaceuticals and fine chemical industries. For businesses seeking this material, exploring reputable manufacturers and suppliers in China offers a pathway to cost-effective procurement and reliable supply.
