Description

1,1,1-13C-Tripalmitin is a stable isotope-labeled analog of tripalmitin, where the central carbon atom of the glycerol backbone is enriched with carbon-13. This compound is essential as a high-purity internal standard and tracer in metabolic research, lipidomics, and clinical diagnostics, ensuring precise quantification and pathway elucidation. It is primarily used by analytical laboratories, pharmaceutical R&D departments, and academic institutions conducting advanced lipid metabolism studies.

Application

• Quantitative Mass Spectrometry: Serves as a critical internal standard for the accurate LC-MS/MS quantification of triglycerides and their metabolites in biological samples.
• Metabolic Pathway Tracing: Used in 13C isotopic tracer studies to investigate lipid biosynthesis, β-oxidation, and energy metabolism in vivo and in vitro.
• Clinical Diagnostics Development: Employed in the calibration and validation of assays for lipid disorders, such as dyslipidemia and fatty acid oxidation defects.
• Pharmaceutical Research: Facilitates drug metabolism and pharmacokinetic (DMPK) studies for compounds targeting lipid pathways.
• Nutritional Science: Applied in research on fat absorption, digestion, and the metabolic fate of dietary lipids.
• Quality Control Reference: Acts as a certified reference material (CRM) for ensuring the accuracy and precision of analytical methods in contract research organizations (CROs).

Quality Control

Our 1,1,1-13C-Tripalmitin is manufactured under strict quality systems to ensure the highest isotopic and chemical purity for research applications. Each batch is supported by a comprehensive Certificate of Analysis (COA) detailing isotopic enrichment (typically ≥99 atom % 13C), chemical purity (by HPLC), and identity confirmation. We adhere to relevant standards for high-purity reference materials to guarantee reliable and reproducible performance in sensitive analytical methods.

Storage

Preserve in a tightly closed container, protected from light. Store at -20°C or below for long-term stability. Allow the vial to reach room temperature in a desiccator before opening to prevent condensation. The product is stable under these conditions for extended periods.
