Description

Octanoic-8,8,8-D3 Acid is a deuterium-labeled isotopologue of caprylic acid, where three hydrogen atoms at the terminal methyl group are replaced with deuterium. This stable isotope labeling is critical for applications requiring precise molecular tracking and analysis, offering a non-radioactive tracer with distinct spectroscopic properties. It is an essential material for researchers and manufacturers in the pharmaceutical, agrochemical, and analytical chemistry sectors who require high-fidelity internal standards for mass spectrometry, metabolic studies, and reaction mechanism elucidation.

Application

• Internal Standard for Quantitative Analysis: Serves as a high-purity internal standard in GC-MS and LC-MS for the accurate quantification of caprylic acid and related compounds in complex matrices.
• Metabolic Pathway Tracing: Used in pharmacokinetic and metabolic studies to trace the fate of fatty acids and their derivatives in biological systems without isotopic interference.
• NMR Spectroscopy: Provides a useful probe in nuclear magnetic resonance (NMR) spectroscopy due to the distinct signal of deuterium, aiding in structural analysis and reaction monitoring.
• Pharmaceutical Intermediate: Acts as a labeled building block in the synthesis of deuterated active pharmaceutical ingredients (APIs) for drug development and stability testing.
• Agrochemical Research: Employed in the development and environmental fate studies of deuterated pesticides and herbicides.
• Material Science: Used in the research of polymers and surfactants to study mechanisms and kinetics where the labeled moiety provides analytical distinction.
