Description

1,2-Dioctadecanoyl-3-[cis-9-Octadecenoyl]-Rac-Glycerol is a structured triglyceride, specifically a triacylglycerol (TAG) composed of two stearic acid (octadecanoic acid) residues and one oleic acid (cis-9-octadecenoic acid) residue. This compound is of significant commercial interest as a high-purity synthetic lipid standard and a key intermediate for advanced lipid research and formulation. It is essential for industries requiring precise lipid matrices, such as pharmaceutical excipient development, nutritional science, and high-end cosmetic emollients. The product, identified by CAS No. 51195-71-2, is supplied to meet the stringent demands of analytical and formulation laboratories globally.

Application

• Analytical Reference Standard: Used as a primary standard in Gas Chromatography (GC) and High-Performance Liquid Chromatography (HPLC) for the quantification and characterization of complex lipid mixtures.
• Pharmaceutical Excipient Research: Serves as a model compound in the development of lipid-based drug delivery systems (LBDDS) to enhance drug solubility and bioavailability.
• Nutritional Science & Biochemistry: Employed in metabolic studies, enzymatic assays (e.g., lipase activity), and as a substrate to investigate lipid digestion and absorption pathways.
• Cosmetic & Personal Care Formulation: Acts as a high-purity emollient and texture modifier in premium skincare products, providing stable lipid layers.
• Biomedical Research: Utilized in cell culture media and as a component in synthetic lipid bilayers for membrane biophysics studies.
• Food Science: Applied in research focused on fat structuring, crystallization behavior, and the development of specialized nutritional lipids.

Quality Control

Our high-purity lipid standards are manufactured under controlled conditions and undergo rigorous analytical testing to ensure identity, purity, and consistency. Each batch is characterized using techniques including HPLC, GC, and NMR spectroscopy. A comprehensive Certificate of Analysis (COA) is provided, detailing assay purity, impurity profile, and physical constants. We support compliance with relevant ISO 9001 quality management standards, and our processes are designed to meet the exacting requirements of research and analytical applications.

Storage

Preserve in a tightly closed container, protected from light. Store at -20°C or below for long-term stability. Under these conditions, the product is typically stable for at least two years. For short-term use (up to one month), storage at 2-8°C is acceptable. Allow the sealed container to equilibrate to room temperature before opening to prevent condensation and moisture absorption.
