Description

Octanoic 1-13C Acid is a stable isotope-labeled analog of caprylic acid, where a carbon-13 atom is incorporated at the carboxyl position. This precise labeling is critical for applications requiring high sensitivity and accurate metabolic or chemical pathway tracing. It is an essential tool for researchers and quality control specialists in the pharmaceutical, agrochemical, and advanced material science industries who rely on isotopic dilution mass spectrometry and NMR spectroscopy.

Application

• Isotopic Tracer Studies: Used as an internal standard in quantitative mass spectrometry (GC-MS, LC-MS) for the accurate analysis of octanoic acid and related compounds in complex matrices.
• Metabolic Research: Enables the detailed study of fatty acid metabolism, β-oxidation pathways, and energy production in biological systems.
• Pharmaceutical Development: Serves as a labeled precursor in the synthesis of deuterated or 13C-labeled drug candidates for pharmacokinetic and bioavailability studies.
• Food & Flavor Analysis: Employed in the precise quantification of short-chain fatty acids in food products, nutritional studies, and flavor chemistry.
• Material Science: Acts as a building block for synthesizing specialty polymers and surfactants with labeled moieties for structural analysis and degradation studies.
• Environmental Science: Facilitates tracing the environmental fate and biodegradation of organic compounds.
