Description

Butanoic Acid-2-13C is a stable isotope-labeled analog of butyric acid, where the carbon atom at the 2-position is enriched with the 13C isotope. This precise labeling makes it an indispensable tool for advanced analytical research, providing a reliable internal standard for quantitative mass spectrometry and enabling detailed metabolic pathway tracing. It is primarily required by research institutions, pharmaceutical developers, and analytical laboratories engaged in metabolomics, pharmacokinetic studies, and the development of diagnostic assays.

Application

• Internal Standard for Quantitative Analysis: Used in GC-MS and LC-MS for the accurate quantification of butyric acid and related metabolites in complex biological matrices.
• Metabolic Pathway Tracing: Enables the study of short-chain fatty acid metabolism, gut microbiome function, and energy homeostasis in biological systems.
• Pharmaceutical Research & Development: Supports drug metabolism and pharmacokinetic (DMPK) studies for compounds interacting with fatty acid pathways.
• Clinical Diagnostics: Serves as a critical component in the development of high-precision diagnostic tests for metabolic disorders.
• Nutritional Science Research: Facilitates studies on dietary fiber fermentation and the production of beneficial microbial metabolites in the gut.
• Isotope Dilution Mass Spectrometry (IDMS): Provides the gold-standard method for achieving high accuracy and precision in analytical measurements.

Quality Control

Our Butanoic Acid-2-13C is manufactured under strict quality control protocols to ensure exceptional isotopic and chemical purity, meeting the exacting requirements of analytical and research applications. Each batch is accompanied by a comprehensive Certificate of Analysis (COA) detailing parameters such as isotopic enrichment, chemical purity (by GC or HPLC), and identity confirmation. We adhere to relevant industry standards for high-purity reference materials.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated place. Due to its highly volatile nature, ensure containers are securely sealed and stored upright. Recommended storage temperature is 2-8°C for long-term stability.
