Description

Butyric-1-13C Acid is a stable isotope-labeled derivative of butyric acid, where a carbon-13 atom is incorporated at the 1-position. This precise labeling is critical for applications requiring high-fidelity molecular tracing and quantification. It is an essential tool for researchers and manufacturers in the pharmaceutical, biotechnology, and advanced chemical synthesis sectors who require isotopically pure materials for metabolic studies, analytical standards, and NMR spectroscopy.

Application

• Metabolic Pathway Research: Used as a tracer in in vitro and in vivo studies to elucidate the metabolism of short-chain fatty acids.
• Analytical Reference Standard: Serves as an internal standard for the accurate quantification of butyric acid and related compounds via GC-MS or LC-MS.
• NMR Spectroscopy: Provides a distinct signal for structural elucidation and dynamic studies of complex biochemical systems.
• Pharmaceutical Development: Employed in the synthesis of isotopically labeled drug candidates for pharmacokinetic and mass balance studies.
• Nutritional Science: Used in research on gut microbiota and the role of butyrate in health and disease.
• Chemical Synthesis: Acts as a labeled building block for the preparation of more complex 13C-labeled organic molecules.

Quality Control

Every batch of our Butyric-1-13C Acid is produced and analyzed under strict quality management protocols to ensure exceptional isotopic and chemical purity, which is paramount for sensitive research applications. We provide comprehensive Certificates of Analysis (COA) detailing isotopic enrichment (typically >99 atom % 13C), chemical purity, and specific analytical results from techniques such as NMR, MS, and HPLC. Our quality commitment aligns with the stringent requirements of research and development in regulated environments.

Storage

Preserve in a tightly closed container, protected from light. Store at 2-8°C under an inert atmosphere (e.g., nitrogen or argon) to minimize oxidation and degradation. The container should be kept in a cool, dry, well-ventilated area separate from bases and oxidizing agents. For long-term stability, avoid repeated warming to room temperature.
