Overview

Iron(3+) trinitrate nonahydrate (CAS 7782-61-8) is a crystalline iron salt hydrate with strong oxidizing properties and high water solubility. This ferric nitrate compound represents one of the most important water-soluble iron salts used across multiple industrial sectors. The nonahydrate form contains nine molecules of crystallization water, giving it exceptional stability under ambient conditions while maintaining excellent dissolution characteristics in aqueous solutions. Its molecular formula FeH18N3O18 reflects the complex hydrated structure that makes this compound particularly valuable for applications requiring readily available iron(III) ions. As a member of the metal nitrate family, iron(3+) trinitrate nonahydrate shares oxidizing characteristics with compounds like barium(2+) dinitrate, though its trivalent iron center provides unique catalytic and chemical properties. The compound appears as violet to brown crystalline material that dissolves readily in water to form acidic solutions due to hydrolysis of the Fe³⁺ ion. The ADR classification 5.1 indicates its oxidizing nature, requiring appropriate handling procedures to prevent contact with combustible materials. While no specific GHS pictograms are assigned, standard precautions for oxidizing agents and corrosive materials should be observed during storage and handling. Primary industrial applications include water treatment processes where it serves as a coagulant and flocculant, catalyst preparation in chemical synthesis, and analytical chemistry as a reagent. The compound also finds use in textile dyeing processes and as an iron source in various chemical manufacturing operations. OYSI maintains reliable supply capabilities for iron(3+) trinitrate nonahydrate to support diverse European industrial requirements with consistent quality standards.
