FAQ

What is Iron oxide (CAS: 1332-37-2)?

Iron oxide (CAS: 1332-37-2) is a chemical compound with the formula Fe₂O₃. It is a reddish-brown, insoluble in water, and thermally stable solid. Commonly known as ferric oxide, it exhibits basic properties and is widely used as a pigment, catalyst, and in various industrial applications. Its chemical structure consists of iron in the +3 oxidation state bonded to oxygen atoms.

What are the main uses of Iron oxide (CAS: 1332-37-2)?

Iron oxide (CAS: 1332-37-2) is primarily used in pharmaceuticals as an iron supplement, in food as a coloring agent (E172), and in industrial coatings, ceramics, and pigments. It also serves as a raw material in the production of other iron compounds and is utilized in research for material science and chemical synthesis due to its stability and reactivity properties.

Is Iron oxide (CAS: 1332-37-2) safe?

Iron oxide (CAS: 1332-37-2) is generally considered safe when handled properly. It has low toxicity in small amounts but may cause irritation if inhaled as dust. Safety standards recommend using protective equipment like gloves and masks during handling. Long-term exposure or ingestion should be avoided, and compliance with OSHA and EPA guidelines is essential for safe use.

How should Iron oxide (CAS: 1332-37-2) be stored?
