Description

Octanoic Acid-7-13C is a stable isotope-labeled analog of caprylic acid, where the carbon-13 atom is specifically incorporated at the 7-position. This precise labeling is critical for advanced analytical applications, providing an internal standard for accurate quantification and metabolic pathway tracing. It is an essential tool for researchers and quality control laboratories in the pharmaceutical, agrochemical, and life science sectors requiring high-fidelity isotopic data.

Application

• Internal Standard for Mass Spectrometry (MS): Used in GC-MS and LC-MS for the precise quantification of caprylic acid and related compounds in complex biological and chemical matrices.
• Metabolic Pathway Tracing: Enables the study of fatty acid metabolism, β-oxidation, and lipid biosynthesis in pharmacological and nutritional research.
• Pharmaceutical Impurity Profiling: Assists in the identification and quantification of process-related impurities and degradants in drug substance and product analysis.
• Clinical Diagnostics: Supports the development of assays for detecting metabolic disorders related to medium-chain fatty acid metabolism.
• Environmental Analysis: Applied as a tracer in studies monitoring the environmental fate and biodegradation of organic compounds.
• Nuclear Magnetic Resonance (NMR) Spectroscopy: Serves as a probe for structural elucidation and dynamic studies in chemical and biochemical systems.
