Ammonium formate cas 540-69-2 purity 99% white solid for reagent use

Ammonium formate (HCOONH₄, CAS 540-69-2) is a white, crystalline, highly water-soluble ammonium salt of formic acid. It is widely utilized as a volatile buffer in liquid chromatography–mass spectrometry (LC–MS) and as a safe, metal-free or metal-catalyzed hydrogen donor in catalytic transfer hydrogenation. The compound decomposes upon heating to release formic acid, ammonia, and hydrogen, exhibiting mild reducing properties while avoiding the handling hazards associated with pressurized H₂. Owing to its high solubility, low UV background, and clean thermal decomposition profile, ammonium formate is extensively applied in pharmaceutical synthesis, fine chemical manufacturing, and analytical chemistry.
