Description

Stearoylarachidonylglycerol is a structured glycerolipid, a monoacylglycerol (MAG) esterified with stearic and arachidonic fatty acids. This specific molecular architecture is of significant interest for advanced research in lipid biochemistry and the development of specialized lipid-based delivery systems. It serves as a critical intermediate or reference standard for scientists and formulators in the pharmaceutical, nutraceutical, and advanced cosmetic industries seeking to leverage the unique properties of structured lipids.

Application

• Biochemical Research: Used as a high-purity reference standard or substrate in enzymatic studies, lipid metabolism research, and signal transduction pathway analysis.
• Pharmaceutical Development: Investigated as a potential component or prodrug in advanced drug delivery systems, including lipid nanoparticles (LNPs) and micellar formulations.
• Nutraceutical Formulation: Serves as a specialized ingredient in the research and development of targeted nutritional supplements and functional foods.
• Cosmetic Science: Employed in R&D for high-performance skincare products, leveraging its lipid structure for enhanced skin barrier function and active ingredient delivery.
• Lipidomics & Analytical Standards: Essential as a calibration standard in mass spectrometry and chromatography for the accurate identification and quantification of complex lipids.
• Synthetic Chemistry Intermediate: Acts as a building block for the chemical synthesis of more complex phospholipids or other bioactive lipid conjugates.

Quality Control

Our Stearoylarachidonylglycerol is produced under stringent quality management protocols. Each batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation via mass spectrometry (MS) and infrared spectroscopy (IR). We provide a detailed Certificate of Analysis (COA) with every shipment, ensuring traceability and compliance with your research or cGMP guidelines for advanced intermediates.

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., argon or nitrogen) to prevent oxidation. Allow the sealed container to reach room temperature before opening to minimize moisture condensation. Keep away from strong oxidizing agents.
