Description

1,2-Dipalmitoyl-Sn-Glycerol CAS NO 761-35-3 is a high-purity synthetic glyceride, specifically a diacylglycerol (DAG) where the sn-1 and sn-2 positions are esterified with palmitic acid. This compound serves as a critical pharmaceutical intermediate and biochemical building block for the synthesis of more complex lipids, including phospholipids and triglycerides. It is essential for researchers and manufacturers in lipidomics, drug delivery systems (liposomes), and specialty chemical synthesis where defined molecular structure and purity are paramount.

Application

• Pharmaceutical Intermediate: Key starting material for the synthesis of phospholipids (e.g., DPPC, DPPG) used in liposomal drug delivery and vaccine formulations.
• Biochemical Research: Essential standard and substrate in lipid metabolism studies, enzyme assays (e.g., lipases), and membrane biophysics research.
• Specialty Chemical Synthesis: Building block for producing structured lipids, surfactants, and other value-added oleochemical products.
• Cosmetic Ingredient Precursor: Used in the manufacture of high-purity emulsifiers and skin-conditioning agents.
• Nutritional Science: Research into the metabolic effects of diacylglycerols (DAGs) as functional food components.

Quality Control

Our 1,2-Dipalmitoyl-Sn-Glycerol is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC for purity and isomer composition, GC for residual solvents, and identity confirmation via IR and MS. We provide full traceability and Certificates of Analysis (COA) are available for every shipment, ensuring compliance with your research and cGMP-grade material requirements.

Storage

Preserve in a tightly closed container, protected from light. Store at 2-8°C under an inert atmosphere (e.g., nitrogen or argon) to prevent oxidation. The material is light-sensitive and easily oxidized; prolonged exposure to air, heat, or light should be avoided. Keep the container sealed in a cool, dry, and well-ventilated place.
