Description

Ferrous Chloride Tetrahydrate is an inorganic salt of iron, widely recognized for its role as a versatile reducing agent and precursor in industrial chemistry. Its value lies in providing a soluble and bioavailable source of ferrous (Fe²⁺) ions, which is critical for numerous chemical synthesis and treatment processes. This product is essential for industries ranging from wastewater management and metallurgy to pharmaceutical and fine chemical manufacturing, where controlled iron introduction is required.

Application

• Wastewater Treatment: Acts as a highly effective coagulant and reducing agent for phosphate removal, odor control, and the precipitation of heavy metals.
• Chemical Synthesis: Serves as a key precursor for the production of other iron compounds, including iron oxides, and as a catalyst or reducing agent in organic synthesis.
• Pharmaceutical Intermediates: Used in the synthesis of iron-based pharmaceuticals and nutritional supplements, leveraging its bioavailable ferrous ion.
• Metallurgy & Surface Treatment: Employed in metal surface etching, pickling baths, and as a component in some types of cement and pigments.
• Laboratory & Research: Utilized as a standard or reagent in analytical chemistry and academic research for redox chemistry studies.

Quality Control

Our Ferrous Chloride Tetrahydrate is manufactured under strict quality management protocols. Each batch undergoes rigorous analytical testing to ensure it meets precise chemical and physical specifications. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and impurity profiles is provided with every shipment to guarantee traceability and compliance with your application requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area. Due to its hygroscopic (moisture-sensitive) and easily oxidized nature, it is recommended to minimize exposure to air and moisture. For long-term storage, consider using an inert atmosphere.
