Description

Glyceryl 1,2-Dipalmitate-3-Octanoate-1-13C is a specifically labeled, structured triglyceride where the first glycerol carbon is enriched with the stable isotope carbon-13. This compound matters for researchers and formulators requiring precise metabolic tracing and analytical studies of lipid digestion, absorption, and distribution. It is primarily needed by the pharmaceutical, nutraceutical, and advanced biochemical research sectors for developing and testing lipid-based drug delivery systems and specialized nutritional products.

Application

• Isotopic Tracer in Metabolic Studies: Used as a carbon-13 labeled internal standard for accurate quantification and tracking of medium-chain and long-chain fatty acid metabolism in vivo and in vitro.
• Pharmaceutical Excipient Development: Serves as a model structured lipid for enhancing the bioavailability of poorly water-soluble active pharmaceutical ingredients (APIs) in lipid-based formulations.
• Advanced Nutritional Research: Employed in the study of specialized medical nutrition and infant formula to understand the metabolic fate of specific triglyceride structures.
• Analytical Reference Standard: Provides a high-purity, isotopically labeled standard for mass spectrometry (MS) and nuclear magnetic resonance (NMR) spectroscopy, improving analytical accuracy.
• Biomarker Discovery: Facilitates research into lipidomic biomarkers for various metabolic diseases by enabling precise tracking of lipid pathways.
• Cosmetic & Dermatological R&D: Investigated for its skin barrier function and delivery properties in topical formulations.

Quality Control

Our carbon-13 labeled lipid products undergo rigorous quality testing to ensure isotopic purity and chemical integrity. Each batch is characterized using advanced analytical techniques including NMR and LC-MS. Certificates of Analysis (COA) detailing chemical purity, isotopic enrichment, and impurity profiles are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store at -20°C or below under an inert atmosphere (e.g., argon or nitrogen) to minimize oxidation. Allow the sealed container to reach room temperature before opening to prevent moisture condensation. For long-term storage, keep the primary container in a desiccated environment.
