1. Ammonium formate is the ammonium salt of formic acid, and is a colorless, hydroscopic, crystalline solid. It can be synthesized through treating ammonium carbonate with 85% formic acid. It is widely used in many organic reactions such as Leuckart reaction which is the reductive amination of aldehydes and ketones. It can also be used as a buffer in HPLC and LC/MS test. Moreover, it is also used in palladium on carbon (Pd/C) reduction of functional group. It can also be used for the preparation of formic acid in situ as well as being used to store formic acid.

2. Ammonium formate, NH4HCO2, is the ammonium salt of formic acid. It is a colorless, hygroscopic, crystalline solid.

3. 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.

4. In chemical analysis, especially to ppt base metals from salts of the "noble" metals.

5. Pure ammonium formate decomposes into formamide and water when heated, and this is its primary use in industry. Formic acid can also be obtained by reacting ammonium formate with a dilute acid, and since ammonium formate is also produced from formic acid, it can serve as a way of storing formic acid.
    Ammonium formate can also be used in palladium on carbon (Pd / C) reduction of functional groups. In the presence of Pd / C, ammonium formate decomposes to hydrogen, carbon dioxide, and ammonia.
    Ammonium formate can be used for reductive amination of aldehydes and ketones (Leuckart reaction)
    Ammonium formate can be used as a buffer in high performance liquid chromatography (HPLC), and is suitable for use with liquid chromatography/mass spectrometry (LC/MS). .
