Overview

Iron(3+) trinitrate nonahydrate (CAS 7782-61-8) is an inorganic oxidizing salt characterized by its high solubility in water and crystalline hydrated structure. This ferric nitrate compound represents one of the most important iron-based oxidizing agents in industrial chemistry. The nonahydrate form contains nine molecules of crystallization water, giving it distinctive hygroscopic properties and excellent stability under normal storage conditions. As a member of the metal nitrate family, it shares oxidizing characteristics with compounds like barium(2+) dinitrate, though iron(3+) trinitrate nonahydrate offers unique advantages in specific applications due to iron's catalytic properties. The compound appears as violet to brown crystalline solid that dissolves readily in water, forming acidic solutions due to hydrolysis of the ferric ion. Its classification under ADR Class 5.1 reflects its oxidizing nature, requiring appropriate handling procedures to prevent incompatible material contact. The molecular formula FeH18N3O18 indicates the presence of three nitrate groups coordinated with the iron(3+) center, along with the nine water molecules that contribute to its stability and handling characteristics. Primary industrial applications include its use as an oxidizing agent in organic synthesis, as a mordant in textile dyeing processes, and as a catalyst precursor in various chemical manufacturing operations. The compound also finds application in analytical chemistry and in the preparation of other iron compounds where controlled iron(3+) introduction is required. OYSI maintains reliable supply chains for iron(3+) trinitrate nonahydrate, ensuring consistent quality and availability for European industrial customers requiring this specialized oxidizing compound.
