Ac-D-Ala-OH-d4（Cat No.:S000722） is a deuterated form of Ac-D-Ala-OH (N-Acetyl-D-alanine), where four hydrogen atoms are replaced with deuterium, increasing its molecular stability. This modification makes it highly suitable as an internal standard for precise analytical methods, particularly mass spectrometry and NMR spectroscopy. N-acetyl-d-alanine is a modified amino acid used in peptide synthesis and biochemical studies. The integration of deuterium into Ac-D-Ala-OH-d4 enhances the accuracy of pharmacokinetic and metabolic research, providing clearer insights into its behavior, stability, and interactions in peptide structures within various biological and chemical systems.
