Description

1-Docosanoyl-2-Dodecanoylphosphatidylcholine is a synthetic, chemically defined phospholipid with a precisely engineered fatty acid chain composition. This high-purity lipid is critical for applications requiring consistent molecular structure and performance, offering superior batch-to-batch reproducibility compared to natural extracts. It is primarily utilized by researchers and formulators in the pharmaceutical, biotechnology, and advanced material science sectors for developing liposomal drug delivery systems, creating biomimetic membranes, and as a key component in diagnostic assays.

Application

• Liposomal Drug Delivery: As a primary or supplementary phospholipid component for constructing stable, long-circulating, or targeted liposomes for encapsulating therapeutic agents.
• Biomimetic Membrane Research: Used in the formation of supported lipid bilayers (SLBs) and vesicles to study membrane protein interactions, permeability, and cell signaling mechanisms.
• Diagnostic Reagent Formulation: Serves as a critical raw material in the production of reagents for clinical diagnostics, including immunoassays and cholesterol testing kits.
• Cell Culture & Cryopreservation: Can be incorporated into media supplements or cryoprotectant formulations to enhance cell membrane integrity and viability.
• Cosmetic & Dermal Formulations: Employed in high-end cosmetic products as a skin-identical lipid to improve barrier function, hydration, and active ingredient delivery.
• Reference Standard & Analytical Chemistry: Used as a certified reference material (CRM) for lipidomics research, method development, and quality control in lipid analysis.

Quality Control

Our 1-Docosanoyl-2-Dodecanoylphosphatidylcholine is manufactured under strict quality management systems. Each batch is subjected to comprehensive analytical testing, including HPLC for purity and identity confirmation and mass spectrometry for structural verification, to ensure it meets the stringent requirements for research and formulation. Certificates of Analysis (COA) with full traceability are provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store at -20°C or below under an inert atmosphere (e.g., argon or nitrogen) to prevent oxidation and hydrolysis. For long-term storage, desiccate. Allow the sealed vial to equilibrate to room temperature before opening to minimize moisture condensation.
