Description

Rac-1-Linoleoyl-3-Linolenoyl-Propanetriol is a structured triacylglycerol (TAG) molecule containing both linoleic and linolenic fatty acid moieties. This specific glyceride is valued for its unique lipid profile and serves as a critical intermediate or reference standard in advanced lipid research and product development. It is primarily sought by manufacturers and R&D laboratories in the nutraceutical, pharmaceutical, and specialty chemical sectors. The compound is supplied with a guaranteed Certificate of Analysis to ensure batch-to-batch consistency for your critical applications.

Application

• Biomedical & Nutritional Research: Used as a reference standard or substrate in studies of lipid metabolism, absorption, and the biochemical roles of polyunsaturated fatty acids (PUFAs).
• Nutraceutical Formulation: Serves as a specialized lipid component in the development of structured lipids designed for targeted nutritional and health benefits.
• Pharmaceutical Intermediate: Acts as a key synthetic building block or carrier lipid in the production of lipid-based drug delivery systems (e.g., liposomes, nanoemulsions).
• Analytical Standard: Essential for the calibration and validation of analytical methods (HPLC, GC) used to quantify complex lipid mixtures in food, feed, and biological samples.
• Cosmetic Science: Investigated for its potential emollient and skin-barrier enhancing properties in high-end skincare formulations.
• Biochemical Reagent: Employed as a specific substrate for lipases and other enzymes in enzymatic studies and biocatalytic processes.

Quality Control

Every batch of Rac-1-Linoleoyl-3-Linolenoyl-Propanetriol is produced and analyzed under strict quality management protocols. Our products undergo rigorous purity and identity testing using advanced chromatographic (HPLC, GC) and spectroscopic (NMR, MS) techniques to ensure compliance with research and development standards. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with each shipment to guarantee traceability and support your quality assurance processes.

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., nitrogen or argon) to minimize oxidation. Allow the container to reach room temperature in a dry environment before opening to prevent condensation and moisture uptake.
