Ammoniated mercuric chloride (HgCl2 NH3), with CAS No. 10124-48-8, is a white crystalline compound with a melting point of 383C. It is primarily used in industrial applications, particularly in analytical chemistry and as a reagent in organic synthesis. This compound is produced by the reaction of mercuric chloride with ammonia, yielding a highly pure product. Stored at room temperature in airtight containers, it is sensitive to moisture and light. Industries such as pharmaceuticals, agriculture, and chemical manufacturing utilize ammoniated mercuric chloride for its antiseptic and preservative properties. Due to its toxicity, strict safety precautions are essential during handling and usage.
