Ammonium formate is the ammonium salt of formic acid, an organic ammonium carboxylate with the formula HCO2NH4, widely used as a buffer in biochemical applications, a reducing agent in organic synthesis, and a pH regulator in water treatment. It serves as a volatile buffer in HPLC and LC-MS mobile phases and as a hydrogen donor in catalytic transfer hydrogenation and the Leuckart reaction. CAS 540-69-2, molecular weight 63.06, stable at ambient storage. Labelled with a warning signal word for moderate hazard. Molekula supplies ammonium formate from research to bulk quantities with full documentation and ISO 9001:2015 traceability.
