Description

L-α-Palmitin is a high-purity monoglyceride, specifically the 1-monopalmitin isomer, with the CAS registry number 5309-46-6. This compound serves as a crucial intermediate and functional ingredient in advanced pharmaceutical and nutraceutical formulations, where precise molecular structure and purity are paramount. It is essential for research and production in sectors requiring high-grade lipid components, such as drug delivery systems, cosmetic emulsions, and specialized food science applications.

Application

• Pharmaceutical Excipient: Used as a solubilizer, emulsifier, and absorption enhancer in solid dosage forms and topical preparations.
• Lipid-Based Drug Delivery Systems: A key component in the development of self-emulsifying drug delivery systems (SEDDS) and nanoemulsions to improve bioavailability of poorly soluble APIs.
• Cosmetic Formulations: Acts as a non-ionic emulsifier and emollient in creams, lotions, and other personal care products for stable texture and skin feel.
• Biochemical Research: Serves as a standard or substrate in enzymatic studies, particularly those involving lipases and lipid metabolism pathways.
• Nutraceutical Products: Employed as an emulsifying agent in fat-soluble vitamin supplements and specialized nutritional blends.
• Food Science: Used in research and development of food emulsifiers and texture modifiers, particularly where specific monoglyceride functionality is required.

Quality Control

Our L-α-Palmitin is manufactured under strict quality management systems. Each batch is tested to ensure it meets high-purity standards suitable for pharmaceutical and research applications. We provide comprehensive Certificates of Analysis (COA) detailing identity, purity, and impurity profiles. Specifications can be aligned with customer requirements, including compliance references for research and cGMP-grade materials.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent moisture uptake. For long-term storage, consider using an inert atmosphere to mitigate potential oxidation.
