| Application: | Formic acid can be used as a reagent in the:• Co-Nx-catalyzed one-pot reductive amination of carbonyl compounds with nitro compounds to synthesize secondary amines. • Photoreduction of polycyclic and heterocyclic nitro arenes to corresponding amines. • Pd-catalyzed chemoselective hydrogenation of olefins to saturated hydrocarbons. |
| General description: | Formic acid is a simple carboxylic acid produced by the hydrolysis of methyl formate or formamide or from its salts. It is primarily used in dyeing, textile, leather, rubber, chemical, and pharmaceutical industries. |
