Description

Hexadecanoic Acid-16-13C Acid is a stable isotope-labeled analog of palmitic acid, where the carbon atom at the 16-position is enriched with the 13C isotope. This precise labeling is critical for applications requiring high-fidelity metabolic and analytical tracing. It is an essential research-grade biochemical for scientists in pharmaceutical development, nutritional studies, and metabolic research who require uncompromised isotopic purity and chemical stability for accurate data. The product is supplied under stringent quality controls to ensure reliability in sensitive experimental workflows.

Application

• Metabolic Pathway Tracing: Used as an internal standard in mass spectrometry (GC-MS, LC-MS) to quantify palmitic acid flux and metabolism in biological systems.
• Pharmaceutical Research: Serves as a labeled precursor in the study of drug metabolism, lipid-based drug formulations, and pharmacokinetics.
• Nutritional Science: Enables precise investigation of fatty acid absorption, distribution, and utilization in animal and human studies.
• Biochemical Synthesis: Acts as a building block for the synthesis of more complex 13C-labeled lipids, surfactants, or esters for research purposes.
• Environmental & Agricultural Studies: Applied in tracing the fate and biodegradation of fatty acids in environmental samples or soil ecosystems.
• Quality Control & Reference Standards: Functions as a certified reference material (CRM) for calibrating analytical instruments and validating methods in analytical laboratories.

Quality Control

Every batch of Hexadecanoic Acid-16-13C Acid is manufactured and analyzed under a strict quality management system. We guarantee high chemical and isotopic purity, with comprehensive testing including assay, isotopic enrichment, and identification. A detailed Certificate of Analysis (COA) is provided with each shipment, documenting the specific results for that lot. Our quality commitment ensures the material meets the exacting standards required for advanced research and analytical applications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at 15-25°C. This product is hygroscopic (moisture-sensitive); ensure the container is sealed tightly after each use to prevent absorption of atmospheric moisture. For long-term storage, consider storing under an inert atmosphere.
