Description

Pentanoic Acid-1-13C is a stable isotope-labeled analog of valeric acid, where the carbon-13 isotope is specifically incorporated at the 1-position. This precise labeling is critical for applications requiring high sensitivity and accurate quantification in analytical research. It serves as an essential internal standard and tracer in metabolic studies, pharmaceutical development, and environmental analysis. Researchers and quality control laboratories in the pharmaceutical, agrochemical, and academic sectors rely on this compound for advanced mass spectrometry and NMR spectroscopy.

Application

• Internal Standard for Mass Spectrometry (MS): Used for the precise quantification of valeric acid and related compounds in complex biological and environmental matrices.
• Metabolic Pathway Tracer: Enables the detailed study of fatty acid metabolism, β-oxidation cycles, and energy production pathways in biochemical and pharmacological research.
• Pharmaceutical Impurity Profiling: Aids in the identification and quantification of process-related impurities and degradants in drug substance and product analysis.
• NMR Spectroscopy Studies: Provides a non-radioactive, stable isotopic label for structural elucidation and dynamic studies of molecular interactions.
• Environmental Analysis: Employed as a tracer in studies monitoring the degradation and fate of organic acids in environmental systems.
• Biomedical Research: Facilitates investigations into gut microbiome metabolites, short-chain fatty acid signaling, and related disease mechanisms.

Quality Control

Every batch of Pentanoic Acid-1-13C is manufactured and tested under strict quality management systems to ensure exceptional isotopic and chemical purity. Our products undergo rigorous quality testing, including NMR and GC/MS analysis, to ensure compliance with industry standards for isotopic enrichment and chemical identity. Certificates of Analysis (COA) detailing isotopic purity, chemical purity, and specific analytical results are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated place away from heat sources and incompatible materials such as strong bases and oxidizing agents. Due to its nature as a strong acid/organic solvent and highly volatile compound, ensure containers are kept upright and sealed when not in use. Recommended storage temperature is 2-8°C for long-term stability.
