Description

Butanoic Acid-13C4 is a stable isotope-labeled analog of butyric acid, where all four carbon atoms are the carbon-13 isotope. This high-purity labeled compound is essential for advanced analytical research, providing an internal standard for precise quantification and metabolic pathway tracing. It is a critical reagent for scientists in pharmaceutical development, environmental analysis, and nutritional biochemistry who require uncompromised accuracy and isotopic purity in their mass spectrometry and NMR studies.

Application

• Internal Standard for Quantitative Analysis: Used in Gas Chromatography-Mass Spectrometry (GC-MS) and Liquid Chromatography-Mass Spectrometry (LC-MS) for the accurate quantification of butyric acid in complex matrices.
• Metabolic Pathway Tracing: Enables the study of short-chain fatty acid metabolism, gut microbiome function, and energy homeostasis in biomedical and nutritional research.
• Pharmaceutical Impurity Profiling: Serves as a reference standard in the development and quality control of pharmaceutical products to identify and quantify related substances.
• Environmental and Food Safety Testing: Employed in analytical methods to detect and measure butyric acid and its derivatives in environmental samples and food products.
• NMR Spectroscopy Studies: Provides a non-radioactive tracer for investigating molecular structures and reaction mechanisms using 13C Nuclear Magnetic Resonance spectroscopy.
• Biochemical Research: Utilized in enzymatic assays and studies of fatty acid oxidation and synthesis pathways.
