Description

Iron(+2) Cation, also known as ferrous ion, is a fundamental inorganic species with the CAS registry number 10179-73-4. It serves as a critical precursor and active component in numerous industrial and research processes where divalent iron chemistry is required. This product is essential for manufacturers and R&D facilities in sectors such as water treatment, catalyst synthesis, and the production of iron-based pigments and nutritional supplements.

Application

• Water & Wastewater Treatment: Acts as a coagulant and reducing agent for the removal of contaminants like phosphates, heavy metals, and colorants.
• Catalyst & Reagent Synthesis: Serves as a key starting material for preparing heterogeneous catalysts, homogeneous complexes, and various ferrous salts.
• Nutritional & Pharmaceutical Industries: Used in the formulation of iron supplements and fortification compounds to address dietary deficiencies.
• Chemical Manufacturing: A fundamental intermediate in the production of iron oxides, pigments (e.g., Prussian blue), and other specialty iron compounds.
• Laboratory & Analytical Research: Employed as a standard or reagent in analytical chemistry, environmental testing, and biochemical studies.
• Electroplating & Surface Treatment: Provides a source of Fe²⁺ ions for electroplating baths and surface conversion coatings.

Quality Control

Our Iron(+2) Cation products are manufactured and handled under strict quality management protocols to ensure batch-to-batch consistency and reliability. Quality is verified through a suite of analytical techniques, including titration and spectroscopic methods, to confirm identity, assay, and impurity profiles. A Certificate of Analysis (COA) detailing all relevant specifications is provided with each shipment to support your quality assurance requirements.

Storage

Preserve in a tightly closed container, protected from light. Due to its properties of being easily oxidized (store under inert atmosphere) and hygroscopic (moisture-sensitive), the material must be stored in a cool, dry place under an inert gas (e.g., nitrogen or argon) to prevent degradation. Recommended storage temperature is 15-25°C.
