Ferrous Ammonium Sulfate, identified by the CAS number 10045-89-3, is a fundamental inorganic chemical that plays a critical role in various B2B applications, primarily within analytical chemistry and industrial catalysis. For procurement managers and research scientists, understanding the specifications and sourcing strategies for this compound is essential for ensuring the success of their operations. As a key chemical intermediate, its availability from reliable manufacturers in China is often sought after.

The compound is characterized by its light blue-green crystalline appearance and its solubility in water, while being insoluble in ethanol. This physical state and solubility profile are important considerations for handling and application. A crucial property for its use in analytical chemistry is its relative stability against oxidation, particularly when compared to simple ferrous salts. This stability allows it to be used effectively as a standard for calibrating oxidizing agents, such as potassium permanganate and potassium dichromate, in titration procedures. It is also vital for preparing precise ferrous ion standards, which are used in colorimetric assays and other quantitative measurements.

In addition to its analytical functions, Ferrous Ammonium Sulfate serves as a catalyst in several industrial processes, including polymerization. This dual functionality makes it a highly versatile chemical. When looking to purchase Ferrous Ammonium Sulfate, B2B users should prioritize suppliers that can guarantee a minimum purity of 98%, as this is often a critical requirement for both analytical accuracy and catalytic efficiency. Packaging, typically in 25kg bags, and competitive price are also significant factors in supplier selection.

To ensure a seamless procurement process, it is advisable to partner with established chemical suppliers that have a strong presence in the market and can provide comprehensive documentation, such as Certificates of Analysis (CoA) and Safety Data Sheets (SDS). These documents are crucial for compliance and quality assurance. By focusing on reputable Chinese chemical manufacturers, businesses can secure a consistent supply of high-quality Ferrous Ammonium Sulfate, thereby supporting their critical analytical and industrial synthesis needs. Access to this compound from a reliable source is fundamental for maintaining product quality and operational efficiency.
