Description

1-Linoleoyl-3-Palmitoyl-Rac-Glycerol is a structured triacylglycerol (TAG) molecule, specifically a mixed triglyceride containing linoleic and palmitic fatty acid chains. This compound is of significant interest in advanced lipid research and product development due to its defined molecular structure, which allows for precise study of lipid metabolism, crystallization behavior, and functional properties. It serves as a critical standard, intermediate, or active component for researchers and manufacturers in the pharmaceutical, nutraceutical, and specialty chemical industries seeking to develop or analyze lipid-based formulations with specific nutritional or physical characteristics.

Application

• Biochemical Research Standard: Used as a high-purity reference standard in lipidomics, metabolic studies, and analytical method development for the accurate identification and quantification of complex lipids.
• Pharmaceutical Excipient Development: Serves as a model structured lipid for investigating drug solubility, bioavailability enhancement, and the formulation of lipid-based drug delivery systems (e.g., self-emulsifying drug delivery systems - SEDDS).
• Nutraceutical & Functional Food Ingredient: Acts as a specialized intermediate or component in the synthesis of structured lipids designed for targeted nutritional applications, such as infant formula or medical nutrition products.
• Cosmetic & Personal Care Formulations: Employed in the development of high-end skincare products for its emollient properties and as a carrier for active ingredients, contributing to skin barrier function.
• Material Science Studies: Utilized to study the physical properties of fats, including polymorphism, melting profile, and crystallization kinetics, which are critical for food science and industrial fat applications.
• Chemical Synthesis Intermediate: Provides a defined starting material for the organic synthesis of more complex lipid derivatives, phospholipids, or labeled compounds for research purposes.

Quality Control

Our 1-Linoleoyl-3-Palmitoyl-Rac-Glycerol is produced and handled under a strict quality management system. Each batch undergoes comprehensive analytical testing to ensure identity, purity, and consistency. We provide detailed Certificates of Analysis (COA) that include data from techniques such as HPLC, GC, and NMR to verify specification compliance. For research and development purposes, we can supply material to meet specific purity grades, including analytical standard grade.

Storage

Preserve in a tightly closed container, protected from light. For long-term storage, keep under an inert atmosphere (e.g., nitrogen or argon) at -20°C or below to minimize oxidation. Allow the container to reach room temperature in a desiccator before opening to prevent moisture condensation. Store away from strong oxidizing agents.
