Description

Iron, Ion (Fe2+) refers to the ferrous ion, a soluble and bioavailable form of iron essential for numerous biological and industrial redox processes. Its primary commercial value lies in its role as a critical precursor and active component in applications ranging from nutritional supplements to advanced material synthesis. This product is particularly vital for manufacturers in the pharmaceutical, nutraceutical, water treatment, and chemical catalyst industries who require a reliable source of high-purity ferrous ions.

Application

• Nutritional Fortification: As a key ingredient in dietary supplements and food fortification to address iron deficiency.
• Pharmaceutical Intermediates: Used in the synthesis of iron-based active pharmaceutical ingredients (APIs) and hematinics.
• Water & Wastewater Treatment: Acts as a coagulant and reducing agent for the removal of contaminants like arsenic and chromium.
• Chemical Synthesis & Catalysis: Serves as a catalyst or reducing agent in organic synthesis and industrial chemical processes.
• Agricultural Products: Incorporated into fertilizers and soil amendments to correct iron chlorosis in plants.
• Laboratory Research: Used as a standard or reagent in analytical chemistry and biochemical research.
• Electroplating & Surface Treatment: Provides a source of iron for electroplating baths and surface finishing operations.
• Pigment & Dye Manufacturing: A precursor in the production of iron oxide pigments and certain dyes.

Quality Control

Our Iron, Ion (Fe2+) products are manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing to ensure it meets precise specifications for identity, purity, and concentration. We provide comprehensive Certificates of Analysis (COA) with each shipment, detailing key parameters such as assay, impurity profiles, and solution stability. Specifications can be tailored to meet various standards, including USP-NF, FCC, or customer-specific requirements.

Storage

Preserve in a tightly closed container, protected from light. Due to its property of being easily oxidized, it is recommended to store under an inert atmosphere (e.g., nitrogen or argon) when in solution or as a sensitive solid salt. Store at controlled room temperature (typically 15-25°C) in a cool, dry, well-ventilated area away from incompatible materials.
