Description

1,2-Dipalmitoyl-Rac-Glycerol CAS NO 40290-32-2 is a high-purity synthetic glyceride, specifically a diacylglycerol (DAG) esterified with palmitic acid. This compound serves as a critical intermediate and reference standard in advanced lipid research and pharmaceutical development. It is essential for scientists and manufacturers in the pharmaceutical, nutraceutical, and specialty chemical industries who require well-defined lipid molecules for drug delivery systems, metabolic studies, and the synthesis of complex phospholipids.

Application

• Pharmaceutical Intermediate: A key building block in the synthesis of more complex phospholipids and prodrugs for enhanced drug delivery and bioavailability.
• Biochemical Research: Used as a standard or substrate in enzymatic studies, lipid metabolism research, and signal transduction pathway analysis.
• Liposome & Nanoparticle Formulation: Acts as a component in the creation of lipid-based carriers for targeted drug and gene delivery applications.
• Reference Standard: Serves as a high-purity analytical standard for quality control and method development in chromatographic assays (HPLC, GC).
• Nutraceutical Development: Investigated for use in functional food and supplement formulations due to its role as a diacylglycerol.
• Cosmetic Ingredient: Employed in high-end skincare formulations as an emollient and skin-identical lipid to support barrier function.

Quality Control

Every batch of our 1,2-Dipalmitoyl-Rac-Glycerol is manufactured and tested under strict quality management systems. We provide comprehensive analytical data to ensure identity, purity, and consistency, meeting the stringent requirements for research and pharmaceutical applications. A detailed Certificate of Analysis (COA) is supplied with each shipment, documenting key parameters such as assay, identity, and impurity profiles.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen or argon) at 2-8°C to minimize oxidation. For long-term storage, keep the sealed container at -20°C. Allow the product to reach room temperature in a desiccator before opening to prevent moisture condensation.
