Hydroxylammonium chloride is a white crystalline inorganic salt, commonly used as a source of hydroxylamine in laboratory and pharmaceutical applications. It acts as a reducing agent and intermediate in organic synthesis.
🏭⚗️ Production
It is produced by neutralizing hydroxylamine with hydrochloric acid under controlled conditions, resulting in the stable crystalline salt form that is easier to handle and store compared to free hydroxylamine.
🔬 Properties
The chemical formula is NH₃OH·HCl with a molar mass of approximately 68.49 g/mol. It appears as white, odorless crystals that are soluble in water but less soluble in alcohol. It is stable under normal conditions but decomposes upon heating, releasing toxic gases including nitrogen oxides.
🧪 Applications
Hydroxylammonium chloride is widely used as a reducing agent in organic synthesis, in the preparation of oximes, hydroxamic acids, and other nitrogen-containing compounds. It is also used in pharmaceuticals as an intermediate and in laboratory redox reactions.
⚠️ Safety
This compound is toxic and can be harmful if ingested, inhaled, or absorbed through skin. It may cause irritation to eyes, skin, and respiratory tract. Proper personal protective equipment such as gloves, goggles, and masks should be worn during handling. It should be stored in a cool, dry place away from heat, acids, and oxidizers.
