Description

1,3-Diheptadecanoyl-2-Oleoyl-Rac-Glycerol is a structured triglyceride (TAG) with a specific fatty acid composition at the sn-1, sn-2, and sn-3 positions of the glycerol backbone. This precise molecular architecture is critical for applications requiring defined lipid behavior and metabolic pathways. It serves as a high-value synthetic intermediate and reference standard for researchers and manufacturers in the pharmaceutical, nutraceutical, and advanced lipid research sectors.

Application

• Pharmaceutical Research: Used as a key intermediate in the synthesis of specialized lipid-based drug delivery systems, such as solid lipid nanoparticles (SLNs) and nanostructured lipid carriers (NLCs).
• Biochemical Standard: Acts as a high-purity analytical reference standard for calibrating instruments and validating methods in lipidomics and metabolic studies.
• Nutraceutical Development: Employed in the formulation of structured lipids designed for specific nutritional or medical purposes, including infant formula and clinical nutrition products.
• Cosmetic Science: Serves as a functional emollient and structuring agent in high-end skincare formulations, contributing to texture and stability.
• Chemical Synthesis: Provides a defined starting material for the organic synthesis of more complex glycerides, phospholipids, or other ester derivatives.

Quality Control

Our 1,3-Diheptadecanoyl-2-Oleoyl-Rac-Glycerol is produced under strict quality management systems. Each batch undergoes comprehensive analytical testing, including chromatography (HPLC, GC) and spectroscopic methods, to ensure identity, purity, and consistency. Certificates of Analysis (COA) with detailed batch-specific results are provided to support your research and quality assurance protocols.

Storage

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