Description

Trilinolein CAS NO 537-40-6 is a triglyceride where all three fatty acid chains are linoleic acid, a polyunsaturated ω-6 fatty acid. This specific molecular configuration makes it a valuable high-purity standard and a critical raw material for research and specialized synthesis. It is essential for industries requiring precise lipid components for nutritional studies, pharmaceutical development, and advanced material science. Our supply ensures consistent quality and reliable availability for your most demanding applications.

Application

• Analytical Reference Standard: Used as a high-purity standard in chromatography (HPLC, GC) for the identification and quantification of triglycerides and fatty acid profiles in complex matrices.
• Biochemical & Nutritional Research: Serves as a defined substrate or model compound in studies of lipid metabolism, oxidation kinetics, and the nutritional impact of specific triglyceride structures.
• Pharmaceutical Excipient Development: Investigated for use in lipid-based drug delivery systems (e.g., self-emulsifying drug delivery systems - SEDDS) to enhance the solubility and bioavailability of poorly water-soluble active pharmaceutical ingredients (APIs).
• Cosmetic & Personal Care Formulations: Acts as an emollient and conditioning agent in high-end skincare products, leveraging its lipid-replenishing properties.
• Specialty Chemical Synthesis: Employed as a building block for the synthesis of structured lipids, modified fats, and other oleochemical derivatives with tailored functional properties.
• Food Science Research: Utilized in studies focused on fat crystallization, oxidative stability, and the functional roles of specific triglycerides in food products.

Quality Control

Every batch of Trilinolein is produced and controlled under a strict quality management system. We provide comprehensive analytical documentation to support your regulatory and research needs. A detailed Certificate of Analysis (COA) is supplied with each shipment, confirming identity, purity, and conformance to agreed specifications. Our quality commitment ensures material traceability and consistency for your critical applications.

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 2-8°C to minimize oxidation. Allow the container to reach room temperature before opening to prevent moisture condensation. Store away from strong oxidizers and heat sources.
