Application

Butyric-d7 acid is a stable isotope and deuterated form of butyric acid, wherein all the alkyl protons are replaced by deuterium. It can be used as an internal standard in:
  • The quantitative analysis of vegetable oils and fats using the LC-MS technique.
  • The analysis of short-chain fatty acids (SCFAs) of renal samples of mice using the GC-MS technique.
