Description

1,3-Dilinolenin is a structured triglyceride where two linolenic acid moieties are esterified at the sn-1 and sn-3 positions of the glycerol backbone. This specific molecular configuration is of significant interest for its unique physicochemical properties and metabolic behavior compared to random triglycerides. It serves as a critical high-purity reference standard and a valuable synthetic intermediate for researchers and manufacturers in the life sciences and specialty chemicals sectors, particularly for lipidomics, nutritional studies, and the development of structured lipids with targeted functionalities.

Application

• Analytical Reference Standard: Used as a high-purity calibrant in chromatography (HPLC, GC) and mass spectrometry for the identification and quantification of complex lipids in biological and food matrices.
• Biochemical Research: A key substrate for studying enzyme specificity (e.g., lipases), lipid metabolism pathways, and the biological effects of specific fatty acid positioning in triglycerides.
• Nutritional Science: Investigated for its role in the formulation of structured lipids aimed at improving the bioavailability of ω-3 fatty acids or designing specialized nutritional products.
• Pharmaceutical Intermediates: Serves as a building block in the synthesis of more complex lipid-based drug delivery systems, such as liposomes or lipid nanoparticles (LNPs).
• Cosmetic & Personal Care: Potential use as an emollient or functional ingredient in high-end skincare formulations, leveraging the properties of linolenic acid.

Quality Control

Every batch of 1,3-Dilinolenin (CAS 195711-48-9) is manufactured and analyzed under strict quality management protocols. We employ advanced analytical techniques including HPLC and GC to ensure identity, purity, and consistency. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and impurity profiles is provided with each shipment to support your research and quality assurance requirements.

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., argon or nitrogen) to minimize oxidation. Allow the sealed container to reach room temperature before opening to prevent moisture condensation.
