Iron(III) nitrate nonahydrate

Iron(III) nitrate nonahydrate (CAS 7782-61-8 ), commonly referred to as iron nitrate, is a crystalline iron salt that supplies bioavailable ferric iron and nitrate in a single, water-soluble compound.

It functions primarily as an oxidizing agent, catalyst precursor, and micronutrient source across industrial and agricultural applications. In water treatment, it acts as a coagulation aid and chemical oxidant.

This compound supports the removal of phosphates, sulfides, and heavy metals from municipal and industrial effluent streams. Agricultural formulators use it as a soluble iron source in fertigation programs and foliar sprays.

It is effective for correcting iron deficiency in high-pH soils where less soluble iron forms fail to perform. Catalyst manufacturers rely on it as a precursor for iron oxide catalysts used in ammonia synthesis.

It is also utilized in Fischer-Tropsch processes and dehydrogenation reactions. Pharmaceutical and laboratory applications include its use as a reagent in synthesis and analytical testing where a controlled ferric ion source is required.

Iron(III) nitrate nonahydrate is supplied as pale violet to colorless crystalline granules or lumps. Standard commercial grades include technical and laboratory-reagent (LR) specifications for various uses.

Purity levels typically range from 98% to 99%+. Packaging is available in bags, drums, and bulk quantities suited to industrial procurement volumes, ensuring reliable supply chains for large-scale operations.
