Aplicaciones

Ammonium formate is widely used in various organic reactions like Leuckart reaction which involves the reductive amination of aldehydes and ketones. It serves as a buffer in high performance liquid chromatography (HPLC) and liquid chromatography-mass spectrometry (LC/MS). It finds application in palladium on carbon (Pd/C) reduction of functional groups. For example, reduction of alkenes to alkanes and formaldehyde to methanol. It is also used to prepare formic acid insitu as well as used to store formic acid by making it as an ammonium salt.

Notas

Hygroscopic. Incompatible with strong acids and strong oxidizing agents.
