For professionals in the chemical and agricultural industries, a thorough understanding of product specifications is fundamental to successful procurement and application. Ferric Ammonium EDTA, a vital chelating agent, offers distinct chemical properties that dictate its efficacy in various uses, from advanced fertigation systems to specialized industrial processes. This guide aims to elucidate these properties and specifications, aiding buyers in their selection of high-quality Ferric Ammonium EDTA from reliable manufacturers and suppliers.

Ferric Ammonium EDTA, with the molecular formula C10H12N2O8FeNH4 and a molecular weight of approximately 362.1, is characterized by its stability as a chelate. This means the iron ion (Fe) is securely bound within the EDTA molecule, preventing it from undergoing unwanted reactions or becoming insoluble in different pH environments. This stability is critical for its function, especially in agricultural applications where consistent iron availability to plants is crucial. When you buy Ferric Ammonium EDTA, you are essentially acquiring a protected, readily usable form of iron.

Key specifications that buyers should look for include the appearance, which is typically a brownish-red viscous liquid. The assay, indicating the concentration of Ferric Ammonium EDTA or total active iron (often expressed as m/m %), is a primary determinant of product quality and efficacy. For instance, a specification of ≥6.0% for total active iron is common for agricultural grades. Other important parameters include the pH of a solution (e.g., 6.5-8.5 for a 1% solution), specific gravity, and the percentage of water-insoluble matter, which should be very low (e.g., ≤0.05%) for high-purity products.

Furthermore, buyers should pay attention to the Fe2+ content, which ideally should be minimal (≤0.1%), as this indicates potential oxidation and reduced product stability. The presence of free chelating agents, like free DTPA (if applicable to the specific product variant), should also be within specified limits. Filtration tests are often included to ensure the absence of particulate matter.

Sourcing Ferric Ammonium EDTA from Chinese manufacturers and suppliers often means accessing these detailed specifications. Reputable suppliers will provide comprehensive documentation, including Material Safety Data Sheets (MSDS) and Certificates of Analysis (COA), detailing all relevant chemical properties. Understanding these parameters empowers buyers to make informed decisions, ensuring they purchase Ferric Ammonium EDTA that perfectly matches their application requirements, whether for agricultural productivity or industrial chemical processes. Obtaining a competitive price from these suppliers further enhances the value proposition.
