Formic acid (HCOOH) is the simplest carboxylic acid and occurs naturally in some ants' venom. It's a colorless liquid with a pungent odor and is widely used in various industrial applications, including as a preservative and antibacterial agent. In the context of catalysis, formic acid is particularly interesting due to its role in hydrogen storage and transfer, as well as being a feedstock for various chemical reactions.
