Ammonium Bifluoride (CAS: 1341-49-7) – High-Purity Inorganic Salt

🧪 CAS Number: 1341-49-7

🌟 Product Description

Ammonium Bifluoride (NH₄HF₂) is a white, crystalline, highly hygroscopic inorganic salt. It is soluble in water and releases hydrofluoric acid upon contact with moisture, making it a powerful etchant and cleaning agent. Widely used in glass treatment, metal surface finishing, oilfield chemicals, and as an intermediate in fluorine-based chemistry.
