Application

Octanoic acid has been used:
  • as a precipitating agent for the purification of antibodies(2)(4)
  • to accelerate β-oxidation for the formation of acetyl-coA akin
  • to increase the rate of astrocyte ketogenesis
  • in chemical 1,1′-carbonyldiimidazole (CDI) coupling of carboxylic acids to coenzyme A (CoA)
