Description

2,3-Butanedione-13C4 is a stable isotope-labeled analog of the flavor compound diacetyl, where all four carbon atoms are the carbon-13 isotope. This product is essential for advanced analytical research, providing an internal standard for precise quantification and metabolic pathway tracing using mass spectrometry. It is primarily needed by analytical laboratories, flavor and fragrance research institutions, and pharmaceutical companies engaged in pharmacokinetic and metabolomic studies.

Application

• Internal Standard for Mass Spectrometry (MS): Serves as a critical quantitative reference in GC-MS and LC-MS analyses of diacetyl and related compounds in complex matrices.
• Metabolic Pathway Tracing: Used in in vitro and in vivo studies to track the absorption, distribution, metabolism, and excretion (ADME) of flavor compounds and diketones.
• Flavor and Fragrance Research: Enables accurate analysis and authentication of butter, cream, and other dairy flavor profiles in food science.
• Pharmaceutical Research: Facilitates pharmacokinetic studies and biomarker discovery where diacetyl or its metabolic products are of interest.
• Environmental and Safety Testing: Used to develop highly sensitive and specific methods for monitoring diacetyl exposure in occupational health and environmental samples.
• Stable Isotope Labeling in Synthesis: Acts as a labeled building block for the synthesis of more complex carbon-13 labeled molecules for research.

Quality Control

Our 2,3-Butanedione-13C4 is produced under controlled conditions to ensure exceptional isotopic and chemical purity, meeting the stringent requirements of analytical research. Each batch is supported by a comprehensive Certificate of Analysis (COA) detailing isotopic enrichment (typically >99 atom % 13C), chemical purity (by GC or HPLC), and identity confirmation (by IR and NMR). We adhere to a rigorous quality management system to guarantee batch-to-batch consistency and reliability for your critical studies.

Storage

Preserve in a tightly closed container, protected from light. Due to its highly volatile nature, store in a cool, well-ventilated place. Recommended storage temperature is 2-8°C (refrigerated) to minimize volatility and maintain stability over extended periods. Keep away from heat and open flame.
