Description

Methyl Heptadecanoate-D33 is a high-purity, deuterium-labeled fatty acid methyl ester, specifically the perdeuterated isotopologue of methyl heptadecanoate. This compound serves as a critical internal standard and reference material in quantitative mass spectrometry and nuclear magnetic resonance (NMR) spectroscopy, enabling precise measurement and analysis of lipid profiles. It is essential for researchers and quality control laboratories in the pharmaceutical, biotechnology, and advanced chemical synthesis sectors, where accurate isotopic tracing and metabolic studies are paramount.

Application

• Quantitative Analytical Standard: Used as an internal standard in GC-MS and LC-MS for the accurate quantification of fatty acids and related lipids in complex biological matrices.
• Metabolic Research: Employed in stable isotope labeling studies to trace lipid metabolism, biosynthesis, and degradation pathways in cellular and animal models.
• NMR Spectroscopy: Serves as a chemical shift reference and a deuterated solvent additive in NMR experiments for structural elucidation.
• Pharmaceutical Development: Utilized in the development and validation of analytical methods for lipid-based drug formulations and metabolomics.
• Biomarker Discovery: Aids in the identification and validation of lipid biomarkers in clinical and diagnostic research.
• Chemical Synthesis: Acts as a labeled building block for the synthesis of more complex deuterated compounds for research purposes.

Quality Control

Our Methyl Heptadecanoate-D33 is manufactured 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 key parameters such as isotopic purity (atom % D), chemical purity (by GC or HPLC), and identity confirmation (by NMR and MS). We adhere to a rigorous quality management system, and specifications can be tailored to support specific research protocols or regulatory submissions.

Storage

Preserve in a tightly closed container, protected from light. Store at 2-8°C (refrigerated) or as specified on the label or COA. Due to its highly volatile nature, ensure containers are securely sealed and stored in a well-ventilated area. For long-term storage under inert atmosphere, please contact us for specific recommendations.
