What is Ferric Ammonium Oxalate？

Ferric Ammonium Oxalate is a coordination compound formed by ferric iron and oxalate ions, typically used as a photographic chemical, reducing agent, and intermediate in various photochemical and light-sensitive applications. It is light-sensitive and decomposes under UV or visible light, making it useful in blueprinting, photoresists, and other imaging technologies.
Its formula is C6H12FeN3O12, and it typically appears as a yellow-green or green crystalline solid, soluble in water and stable under dark, dry conditions.
