Formaldehyde sodium bisulfite hemihydrate is a form of formaldehyde with a chemical structure containing one molecule of water. It is used in the production of animal feed as a nutritional additive that helps animals grow and maintain weight. Formaldehyde also has antibacterial properties, which can be used to treat infectious diseases such as salmonella. It binds to the bacterial cell wall by covalent linkage and prevents the bacteria from growing and reproducing. The aliphatic hydrocarbon group on formaldehyde can be substituted with halides, trifluoroacetic acid, or hydrocarbons to provide different types of formaldehyde salts.
