Description

2,3-Butanedione-D6 is a deuterium-labeled isotopologue of the flavor compound diacetyl, specifically designed for use as an internal standard in analytical chemistry. This high-purity compound is essential for ensuring accurate quantification and method validation in mass spectrometry-based analyses. It is primarily utilized by analytical laboratories, flavor and fragrance manufacturers, and research institutions engaged in metabolomics, food science, and environmental testing where precise isotopic dilution is required.

Application

• Internal Standard for GC-MS/LC-MS: Critical for quantitative analysis of diacetyl and related diketones in complex matrices using isotope dilution mass spectrometry.
• Flavor and Fragrance Research: Used in the development and quality control of butter, cream, and other dairy flavorings to ensure accurate profiling and safety assessment.
• Metabolomic Studies: Serves as a labeled tracer in metabolic pathway analysis to study fermentation processes and microbial production of flavor compounds.
• Food Safety and Regulatory Testing: Enables precise measurement of diacetyl levels in food products and workplace air samples for compliance with health and safety regulations.
• Pharmaceutical Impurity Profiling: Employed in the analysis of pharmaceutical formulations where diacetyl or acetylpropionyl may be present as process-related impurities.
• Environmental Analysis: Aids in the detection and quantification of volatile organic compounds (VOCs) in environmental samples.

Quality Control

Our 2,3-Butanedione-D6 is manufactured under strict quality control protocols to ensure high isotopic purity and chemical stability, essential for reliable analytical results. Each batch is accompanied by a comprehensive Certificate of Analysis (COA) detailing parameters such as isotopic enrichment (atom % D), chemical purity by NMR and GC-MS, and residual solvent content. 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 at room temperature (15-25°C). Due to its highly volatile nature, ensure containers are kept upright and sealed when not in use to prevent evaporation and potential concentration changes.
