For professionals in the fine chemical and pharmaceutical sectors, the acquisition of high-purity raw materials is a critical aspect of operational success. High-purity Gold Powder, identified by CAS number 7440-57-5, is one such material where quality assurance and supply chain reliability are non-negotiable. This guide aims to assist procurement managers and R&D scientists in making informed purchasing decisions.

Understanding the Product: Gold Powder (CAS 7440-57-5)

Gold Powder is prized for its elemental properties, with a molecular formula of Au and a molecular weight of 196.9666. Its physical characteristics, such as a density of 19.3 g/mL at 25°C and zero solubility, make it stable in various applications. The most critical attribute for industrial use is its purity, often specified at ≥99%. This high level of purity is essential for its role as a fine chemical and its potential use as a pharmaceutical intermediate.

When you are looking to buy Gold Powder, scrutinizing the supplier's specifications is paramount. Ensure that the product offered matches the CAS number 7440-57-5 and meets the purity requirements for your specific application. Understanding the physical form – typically a white powder – and its handling properties is also important.

Key Considerations When Choosing a Supplier

Selecting the right manufacturer or supplier for Gold Powder involves several key considerations:

  • Quality Assurance: Does the supplier provide a Certificate of Analysis (CoA) that details the purity, physical properties, and any trace impurities? For pharmaceutical applications, compliance with industry standards is crucial.
  • Supply Chain Reliability: Can the supplier guarantee a consistent and stable supply of Gold Powder? This is especially important for bulk orders. Manufacturers in China, such as NINGBO INNO PHARMCHEM CO.,LTD., often have significant production capacities.
  • Pricing and Payment Terms: Obtain quotes from multiple suppliers to compare pricing. Investigate the payment options available (e.g., L/C, T/T, Paypal) and understand the incoterms (e.g., FOB, CIF) to factor in shipping costs.
  • Technical Support and Service: Does the supplier offer responsive customer service and technical assistance? This can be invaluable when dealing with specialized chemicals.

The Role of Gold Powder in Various Industries

While this document focuses on its potential as a pharmaceutical intermediate, Gold Powder finds applications in other sectors as well. Its unique properties make it valuable in advanced materials research, specialized coatings, and certain catalysts. Therefore, when you search for Gold Powder, consider the broad spectrum of its utility.

How to Initiate a Purchase

To purchase Gold Powder, begin by identifying potential manufacturers and suppliers. Contact them directly to request a quote and discuss your specific needs. Clearly state the product (Gold Powder), CAS number (7440-57-5), required purity, quantity, and any specific packaging requirements. Many suppliers will also ask for your intended application to ensure the product is suitable.

For those looking to buy Gold Powder in China, NINGBO INNO PHARMCHEM CO.,LTD. is a notable supplier that emphasizes quality and customer service. Engaging with such suppliers provides access to cost-effective solutions without compromising on the integrity of the chemical. By following these guidelines, buyers can confidently source high-purity Gold Powder to meet their critical industrial demands.
