Sodium Rhodizonate, scientifically known by its CAS number 523-21-7, is a fine chemical with diverse applications in analytical chemistry and scientific research. As a procurement professional or a research scientist, understanding its fundamental properties, correct handling procedures, and effective sourcing strategies is crucial for efficient laboratory operations. This guide aims to provide essential information for those looking to buy Sodium Rhodizonate.

Key Properties of Sodium Rhodizonate

Sodium Rhodizonate typically presents as a Green-gray to dark green fine crystalline powder. Its physical form is stable under recommended storage conditions, usually at room temperature. A significant characteristic is its solubility in water, which is vital for its use in aqueous analytical procedures. The compound has a high melting point, generally above 300°C, indicating good thermal stability. Its molecular formula is C6Na2O6, with a molecular weight of 214.04 g/mol. Chemically, it is recognized for its reactivity with certain metal ions, leading to distinct color changes that are leveraged in analytical applications like titration and colorimetric detection.

Safe Handling and Storage Recommendations

While Sodium Rhodizonate is a valuable chemical, like all laboratory reagents, it should be handled with appropriate care. Standard laboratory safety practices should be followed, including the use of personal protective equipment (PPE) such as gloves, eye protection, and laboratory coats. Avoid inhalation of dust and ensure adequate ventilation in the workspace. Incompatible materials, such as strong oxidizing agents, should be kept separate. For optimal preservation of its quality and efficacy, it is recommended to store Sodium Rhodizonate in tightly closed containers, typically at room temperature, away from direct sunlight and moisture. Reputable suppliers will provide comprehensive Safety Data Sheets (SDS) detailing all necessary precautions for safe handling, storage, and disposal.

Sourcing Sodium Rhodizonate: What to Look For

When procuring Sodium Rhodizonate (CAS 523-21-7), it is essential to partner with reliable manufacturers and suppliers. Key considerations include:

  • Purity Verification: Always request a Certificate of Analysis (COA) that specifies the purity level (e.g., ≥90% or ≥98%) and other relevant physical and chemical parameters.
  • Supplier Reputation: Choose suppliers with a proven track record in providing high-quality fine chemicals and excellent customer service. Many well-regarded manufacturers are based in China, offering competitive pricing and good export capabilities.
  • Availability and Lead Times: Ensure the supplier can meet your quantity requirements and deliver within your expected timeframe.
  • Technical Support: A supplier that offers technical assistance regarding product specifications and applications can be invaluable for R&D scientists.
  • Sample Provision: Before making a bulk purchase, inquire about the availability of samples to perform your own quality verification.

By carefully considering these factors, procurement professionals can effectively source high-quality Sodium Rhodizonate, ensuring the reliability and accuracy of their laboratory’s analytical results.

In summary, a thorough understanding of Sodium Rhodizonate’s properties, adherence to safe handling practices, and a strategic approach to sourcing from dependable suppliers are fundamental for any laboratory utilizing this important fine chemical. This ensures both operational safety and analytical integrity.
