Description

1-Stearoyl-2-Linoleoyl-3-Oleoyl-Rac-Glycerol is a structured triglyceride composed of stearic, linoleic, and oleic fatty acids, representing a high-purity, well-defined lipid standard. This compound is critical for research and development in lipid science, providing a precise molecular reference for analytical method validation and metabolic studies. It is primarily needed by manufacturers and R&D laboratories in the pharmaceutical, nutraceutical, and advanced food ingredient sectors.

Application

• Biochemical Research Standard: Serves as a critical reference material for the calibration of analytical instruments (e.g., HPLC, GC-MS) in lipidomics and metabolomics.
• Pharmaceutical Excipient Development: Used in the formulation of lipid-based drug delivery systems (LBDDS) to enhance the bioavailability of poorly soluble active pharmaceutical ingredients (APIs).
• Nutraceutical Ingredient: Acts as a structured lipid component in specialized nutritional products and medical foods designed for targeted metabolic pathways.
• Cosmetic Formulation: Employed as an emollient and skin-conditioning agent in high-end skincare products due to its specific fatty acid profile.
• Food Science Research: Utilized as a model compound to study fat crystallization, oxidative stability, and the nutritional impact of specific triglyceride structures.
• Quality Control (QC) Testing: Essential for the internal QC and method validation protocols of companies producing or working with complex lipid mixtures.

Quality Control

Our 1-Stearoyl-2-Linoleoyl-3-Oleoyl-Rac-Glycerol is produced under strict quality management systems. Each batch undergoes rigorous analytical testing, including chromatographic purity assays and identity confirmation, to ensure it meets the high standards required for research and formulation. Certificates of Analysis (COA) with detailed chromatographic data (HPLC/GC) 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., nitrogen or argon) to minimize oxidation. For long-term storage, keep desiccated to prevent moisture uptake. Allow the container to reach room temperature before opening to avoid condensation.
