CAS 10421-48-4 — Ferric Nitrate

Ferric nitrate is an inorganic compound composed of iron, nitrogen, and oxygen, primarily used as a mordant in dyeing and textile processing, as well as in analytical chemistry for iron quantification and water treatment applications. It appears as a dark brown to black crystalline solid or hygroscopic powder, soluble in water and polar solvents. This chemical has a CAS number of 10421-48-4, a molecular formula of Fe(NO₃)₃ (often expressed as FeN₃O₉), and a molecular weight of 241.8597 g/mol. It is non-hazardous under standard conditions with no signal word classification, and it is stable at ambient temperatures when stored properly in a dry, well-ventilated environment. Molekula supplies ferric nitrate from research to bulk quantities with full documentation and ISO 9001:2015 traceability.
