| Use | Used in the pharmaceutical industry In the pharmaceutical industry, biological agents (human albumin) contain sodium caprylate as an inactive ingredient. In terms of biology, higher acid salts are generally used for the special selection of strains. The reason why salts are used is that salts have greater solubility than higher acids themselves. And the PH value is better adjusted. For example, when breeding bacteria that can degrade caprylic acid, sodium caprylic acid needs to be added to the culture medium. In the field of chemistry: sodium caprylate can be used to decarboxylate to produce high-purity n-heptane sodium caprylate is used as a protein stabilizer in biological preparations |
