Description
Ferric chloride anhydrous is a chemical compound composed of iron(III) ions and chloride ions. It is a dark brown, crystalline solid that is highly hygroscopic, meaning it readily absorbs moisture from the air. Ferric chloride anhydrous is commonly used as a Lewis acid catalyst in organic synthesis, particularly in the production of pharmaceuticals, dyes, and perfumes. It is also utilized in wastewater treatment as a coagulant and flocculant to remove impurities and color from water. Additionally, ferric chloride anhydrous finds applications in etching printed circuit boards (PCBs) and as a reagent in various chemical reactions.
