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.
We are committed to bringing you Greener Alternative Products, which adhere to one or more of The 12 Principles of Greener Chemistry. This product has been enhanced for catalysis. Click here for more information.

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.
