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.

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.

Development of a Simple and Rapid Digestion Protocol for Proteomics Sample Preparation

In this study, we developed a rapid trypsin digest kit that, at elevated temperatures, yielded reliable, reproducible results in less than 2 hours on a wide variety of substrates for mass spectrometry.

Our team of scientists has experience in all areas of research including Life Science, Material Science, Chemical Synthesis, Chromatography, Analytical and many others.
