Description

1,2-Dipalmitoyl-Sn-Glycero-3-Phosphate Calcium Salt is a high-purity, synthetic phospholipid derivative, specifically the calcium salt of dipalmitoyl phosphatidic acid. This compound is a critical building block in advanced lipid-based formulations, valued for its role in creating stable, functional membranes and delivery systems. It is essential for researchers and manufacturers in the pharmaceutical, biotechnology, and advanced cosmetics industries developing liposomal drug delivery, diagnostic agents, and high-performance biomimetic materials.

Application

• Liposomal Drug Delivery Systems: A key phospholipid component for constructing stable liposome bilayers to encapsulate and deliver active pharmaceutical ingredients (APIs).
• Biomimetic Membrane Research: Used in model membrane studies (e.g., Langmuir-Blodgett films, vesicles) to investigate membrane biophysics, protein-lipid interactions, and permeability.
• Diagnostic Reagent Formulation: Serves as a stabilizer and functional component in the development of in-vitro diagnostic assays and imaging contrast agents.
• Cosmetic Actives & Advanced Skincare: Incorporated into high-end cosmetic formulations for its biomimetic properties, aiding in the delivery of active compounds and skin barrier repair.
• Biochemical & Cell Culture Supplements: Used as a defined lipid source in specialized cell culture media and biochemical reaction systems.
• Reference Standard & Analytical Chemistry: Employed as a certified reference material (CRM) for quality control and analytical method development in lipidomics and pharmaceutical testing.
