Sodium butyrate (NaOOCCH2CH2CH3) is a popular short chain carboxylate (SCA,
C4). Chemically, sodium butyrate exists as a colorless hygroscopic powder which is
soluble in water, DMSO, ethanol, and methanol. It is formed from the neutralization
of pungent and corrosive butyric acid. The neutralization eliminates bad smell of
butyric acid and forms a neutral, easier to work with product.
Today, sodium butyrate is tied with calcium butyrate as the most preferred butyrate-
based feed additives. However, the higher water solubility of sodium butyrate makes
it the prime material in feed supplements.
Other important applications of sodium butyrate include:
cellulose butyrate esters precursor
detoxifier of ammonia
metabolite
preservative
