Description

1,14-Tetradecanedioic-D24 Acid is a high-purity, deuterium-labeled long-chain dicarboxylic acid, serving as a critical internal standard and tracer in advanced analytical chemistry. Its fully deuterated carbon backbone provides exceptional isotopic purity, minimizing interference in mass spectrometry and NMR studies for precise quantitative analysis. This compound is essential for researchers and quality control laboratories in the pharmaceutical, metabolic research, and material science sectors who require definitive compound identification and accurate measurement.

Application

• Mass Spectrometry Internal Standard: Used as a deuterated internal standard for the accurate quantification of endogenous C14 dicarboxylic acids (e.g., tetradecanedioic acid) in biological matrices via GC-MS or LC-MS.
• Metabolic Pathway Tracing: Enables the study of fatty acid ω-oxidation and peroxisomal β-oxidation pathways in pharmacokinetic and metabolomic research.
• NMR Spectroscopy: Serves as a chemical shift reference and a non-interfering probe in complex mixture analysis due to its distinct deuterium signature.
• Pharmaceutical Impurity Profiling: Aids in the identification and quantification of process-related impurities or degradation products in drug substance development.
• Polymer Science Research: Acts as a labeled monomer or chain extender in the synthesis of deuterated polyesters or polyamides for studying polymer dynamics and structure.
• Environmental Analysis: Functions as a recovery standard in the analysis of dicarboxylic acids in environmental samples.
