用途純粋なギ酸アンモニウムは、加熱するとホルムアミドと水に分解され、これが工業的な主な利用となる。また、ギ酸アンモニウムと希酸を反応させるとギ酸が得られ、ギ酸アンモニウムはギ酸からも作られるため、ギ酸の貯蔵形態としても使われる。 ギ酸アンモニウムは、官能基のパラジウム炭素還元にも用いることができる。パラジウム炭素の存在下で、ギ酸アンモニウムは水素、一酸化炭素、アンモニアに分解される。生成した水素ガスはパラジウムの表面に吸収され、そこで様々な官能基と反応する。例えば、アルケンはアルカンに還元され、ホルムアルデヒドはメタノールに還元される。活性なヘテロ原子―炭素単結合を切断し、水素に置換することもできる(水素化分解)。 ギ酸アンモニウムは、アルデヒドやケトンの還元的アミノ化にも用いることができる(ロイカート反応)。 ギ酸アンモニウムは、高速液体クロマトグラフィーのバッファとして用いることもでき、LC/MSを行うのに適している。ギ酸アンモニウムとアンモニウムイオンの酸解離定数は、それぞれ3.8と9.2である。
使用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. In chemical analysis, especially to ppt base metals from salts of the "noble" metals. 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). .

化学的特性Ammonium formate, NH4HCO2, is the ammonium salt of formic acid. It is a colorless, hygroscopic, 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.Common HPLC Buffers: Ammonium formate (2.7<PH<3.7) does a fairly good job of filling the gap at the low-pH end.
Acidic salts, such as AMMONIUM FORMATE, are generally soluble in water. The resulting solutions contain moderate concentrations of hydrogen ions and have pH's of less than 7.0. They react as acids to neutralize bases. These neutralizations generate heat, but less or far less than is generated by neutralization of inorganic acids, inorganic oxoacids, and carboxylic acid. They usually do not react as either oxidizing agents or reducing agents but such behavior is not impossible. Many of these compounds catalyze organic reactions.

...WITH LARGE DOSES OF...AMMONIUM /SALTS/, THERE ARISES THE POSSIBILITY OF SUFFICIENT ABSORPTION TO PRODUCE DIURESIS & SYSTEMIC AMMONIA POISONING, PARTICULARLY IF MATERIAL IS ADMIN PARENTERALLY. /AMMONIUM SALTS/
純化方法Heat the solid in NH3 vapour and dry it in a vacuum till the NH3 odour is faint (note that it can evaporate completely in a vacuum). Recrystallise it from absolute EtOH and then keep it in a desiccator over 99% H2SO4 in vacuo. It is very hygroscopic. It exists in two forms, stable needles and less stable plates. It also forms acid salts, i.e. HCO2NH4.3HCO2H and HCO2NH4.HCO2H. [Kensall & Adler J Am Chem Soc 43 1473 1921, Beilstein 2 IV 18.]
定義ChEBI: Ammonium formate is the ammonium salt of formic acid. It has a role as a buffer. It is functionally related to a formic acid.
