Description

General description

Acetic acid-d₄ (Tetradeuteroacetic acid), a deuterated carboxylic acid, is the tetradeuterated form of acetic acid. Its dissociation constant has been evaluated in deuterium oxide (D₂O) by an emf method.

Application

Acetic acid-d₄ has been used as a deuterated solvent for the dissolution of internal standard in qNMR (Quantitative Nuclear Magnetic Resonance) quantification experiments.
Acetic acid-d₄ may also be used as a deuterated solvent in the ¹H NMR spectral studies of the following:

• CB2, a CNBr peptide
• α - tocopherol succinate hydrophobically modified chitosan(CS-TOS)
