For procurement professionals and R&D scientists in the B2B chemical and pharmaceutical landscape, understanding the precise specifications of raw materials is fundamental to ensuring successful product development and manufacturing. Sodium Oxalate (CAS 62-76-0) is no exception. As a key supplier and manufacturer, we emphasize the importance of detailed specifications to meet the diverse needs of our clientele. This guide focuses on the critical quality parameters that industrial buyers should consider.

The primary specification for Sodium Oxalate is its assay or purity. Our product consistently meets a minimum of 99.0%. This high purity is essential, particularly for its applications as a primary standard in analytical chemistry, where even minor impurities can lead to significant deviations in results. For industrial uses, such as in textile finishing or ceramic production, a high assay ensures predictable reactions and consistent end-product quality. When you buy Sodium Oxalate from us, you are assured of this stringent purity level.

The appearance of Sodium Oxalate is typically a white powder. This visual characteristic is an initial indicator of quality. While seemingly straightforward, consistency in appearance can reflect the uniformity of the manufacturing process. Deviations from the expected white powder could suggest contamination or variations in particle size, which might impact solubility or reactivity in certain applications.

Beyond the main assay, several impurity limits are crucial for industrial buyers. The provided specifications often include maximum allowable percentages for:

  • Sulfate (SO4): Generally limited to 0.02% Max.
  • Chloride (Cl): Typically capped at 0.02% Max.
  • Iron (Fe): Kept below 0.001% Max for high-purity grades.
  • Ammonium (NH4): Limited to 0.02% Max.
  • Heavy Metals (as Pb): Strict control, often at 0.002% Max.
  • Potassium (K): Kept very low, e.g., 0.005% Max.
These limits are vital for applications where specific ions could interfere with chemical processes or contaminate the final product. As a conscientious manufacturer in China, we meticulously monitor these impurities to ensure our Sodium Oxalate meets global industry standards.

When evaluating a Sodium Oxalate supplier, always request detailed Certificates of Analysis (CoA) that reflect these specifications. Understanding these parameters allows you to make informed decisions, ensuring that the Sodium Oxalate you procure is perfectly suited for its intended purpose, whether it’s for precise laboratory work or demanding industrial processes. We are here to provide the documentation and quality assurance you need to source with confidence.
