Description

Ferrous chloride (CAS 7758-94-3 ), also known as FeCl2 or iron dichloride, is an iron(II) salt used across water treatment, metal processing, and chemical manufacturing. It functions primarily as a coagulant, reducing agent, and catalyst precursor in industrial-scale operations. In municipal and industrial wastewater treatment, it acts as a coagulant and flocculant, precipitating phosphates and heavy metals from effluent streams. Textile and leather processors use it as a mordant to fix dyes and as a reducing agent in dyebath chemistry. These applications improve color fastness and process consistency across various manufacturing sectors. In mining and hydrometallurgy, it supports leaching operations and metal recovery processes where controlled iron chemistry is required for efficiency. Chemical manufacturers also source it as a catalyst precursor for synthesis routes involving iron-based catalytic systems. This versatile chemical is essential for maintaining high standards in modern industrial and environmental management protocols. The product is available in anhydrous powder form and as a tetrahydrate in solid crystalline form. The tetrahydrate is the more common commercial supply format for most global distribution and storage requirements. Liquid solutions of varying concentration are also offered for direct dosing in water treatment applications. Technical grade is the standard specification for most industrial buyers, ensuring reliable performance in large-scale chemical processes. Purity and iron content are strictly verified against supplier certificates of analysis to meet industrial needs. This ensures that every batch complies with the necessary safety and performance benchmarks required by professional chemical engineers. Contact us for supply of Ferrous chloride Request Quote
