Ferric Ammonium Citrate, identified by CAS number 1185-57-5, is a complex coordination compound composed of iron, ammonia, and citric acid. It typically presents as either reddish-brown or green scales or powder, depending on the specific iron content and oxidation state. This chemical is highly soluble in water and is notably characterized by its significant photosensitivity, which dictates specific storage and handling requirements to prevent degradation when exposed to light.
In industrial and research settings, Ferric Ammonium Citrate serves as a versatile source of iron. Its chemical stability under controlled conditions and its ability to act as a reducing agent in certain photochemical reactions make it a valuable raw material. It is widely utilized across various sectors, ranging from traditional imaging techniques to nutritional applications, where it functions as a stable iron supplement. Proper management of its hygroscopic nature is essential for maintaining its efficacy in technical formulations.
