Description

1,3-Didocosanoyl-2-Oleoyl-Rac-Glycerol is a structured triglyceride (TAG) with a specific fatty acid composition, where the sn-1 and sn-3 positions are esterified with behenic acid (docosanoic acid, C22:0) and the sn-2 position with oleic acid (C18:1). This precise molecular architecture is critical for applications requiring controlled lipid behavior and metabolic properties. It serves as a high-value synthetic lipid standard and a key intermediate for advanced research and product development in the life sciences and specialty chemical sectors.

Application

• Biochemical & Nutritional Research: Used as a defined lipid standard for studying fat metabolism, lipid digestion, and the effects of specific triglyceride structures.
• Pharmaceutical Excipient Development: Acts as a model compound for formulating lipid-based drug delivery systems (LBDDS) to enhance the bioavailability of poorly soluble APIs.
• Reference Material: Serves as a high-purity calibrant and reference standard in analytical chemistry, particularly in chromatography (HPLC, GC) and mass spectrometry.
• Specialty Chemical Synthesis: A key building block for synthesizing more complex structured lipids, phospholipids, or other ester derivatives with tailored physical properties.
• Cosmetic Science: Investigated for its potential as a stable, non-greasy emollient or structuring agent in high-end skincare formulations.

Quality Control

Our 1,3-Didocosanoyl-2-Oleoyl-Rac-Glycerol is produced under strict quality management protocols. Each batch is characterized using advanced analytical techniques to ensure identity, purity, and consistency. We provide comprehensive Certificates of Analysis (COA) detailing key parameters such as assay, fatty acid profile, and impurity limits. Specifications can be aligned with research or cGMP-grade requirements upon request.

Storage

Preserve in a tightly closed container, protected from light. Store at -20°C or below under an inert atmosphere (e.g., nitrogen or argon) for long-term stability, as the compound is easily oxidized. For short-term use, store at 2-8°C. Allow the sealed container to reach room temperature before opening to prevent moisture condensation.
