For procurement managers and research scientists in the B2B sector, securing a reliable supply of high-quality chemical reagents is fundamental. Ferrous Ammonium Sulfate (CAS 10045-89-3) is one such compound, vital for its applications in analytical chemistry and as an industrial catalyst. Understanding the nuances of sourcing this chemical from a trusted manufacturer in China is key to ensuring operational continuity and product integrity.

Ferrous Ammonium Sulfate, often recognized by its pale blue-green crystalline appearance, is a double salt with the chemical formula Fe(NH4)2(SO4)2. Its physical properties, such as solubility in water and relative stability at room temperature, make it a practical choice for various applications. However, its sensitivity to air oxidation means that sourcing from a reputable supplier who can guarantee product freshness and purity is essential.

The principal use of Ferrous Ammonium Sulfate is as an analytical reagent. It plays a critical role in volumetric analysis, particularly in titrations where it serves as a primary standard for calibrating oxidizing agents like potassium permanganate. Its ability to provide a stable and pure source of ferrous ions also makes it indispensable for preparing standard solutions used in colorimetric measurements and other quantitative tests. For companies that need to purchase Ferrous Ammonium Sulfate, a high assay (often ≥98%) is a critical specification to ensure accurate and reproducible results.

Beyond the laboratory, Ferrous Ammonium Sulfate finds utility as a catalyst in certain polymerization processes. This industrial application further underscores the demand for a consistent and high-quality supply. When evaluating suppliers, it's important to look for those who can provide comprehensive product documentation, including certificates of analysis, and demonstrate robust quality control measures. Negotiating a competitive price for bulk quantities from a reliable chemical manufacturer is a strategic move for any B2B operation.

In summary, whether you are conducting precise analytical tests or facilitating industrial chemical processes, the quality of your Ferrous Ammonium Sulfate directly impacts your outcomes. Partnering with a knowledgeable and dependable supplier in China ensures you receive a product that meets your exact specifications, backed by competitive pricing and reliable delivery. This strategic procurement approach is vital for maintaining efficiency and excellence in your operations.
