HCOOH, or formic acid, is a colourless, smelly liquid with the chemical formula HCOOH. In some insects, particularly ants, it naturally occurs and is the most basic carboxylic acid. There are many industrial uses for formic acid, including as a preservative and antibacterial agent in silage and livestock feed. It functions as a finishing and dyeing agent in the textile industry. Additionally, it is used in the tanning of leather, the creation of rubber, and as a coagulant in the production of rubber goods. Formic acid is employed in a variety of chemical processes as well as an organic synthesis solvent. But because it is corrosive and dangerous, it needs to be handled carefully and used while taking precautions.
