Description

Stigmastanyl-Phosphorylcholine is a high-purity, synthetic phospholipid derivative of stigmasterol, a plant sterol, conjugated with a phosphorylcholine head group. This unique molecular structure makes it a valuable intermediate and research chemical for developing advanced lipid-based delivery systems and biomimetic membranes. It is primarily sought by researchers and manufacturers in the pharmaceutical, nutraceutical, and advanced materials sectors. Its application is critical for studies in liposome formulation, drug targeting, and membrane biophysics.

Application

• Pharmaceutical Research & Development: As a key component in the formulation of sterol-containing liposomes for targeted drug delivery and vaccine adjuvants.
• Nutraceutical Encapsulation: Used to create specialized lipid vesicles for the enhanced bioavailability and stability of bioactive compounds like plant sterols and fat-soluble vitamins.
• Biomimetic Membrane Studies: Serves as a synthetic analog for constructing model cell membranes to study lipid-protein interactions, membrane fluidity, and signaling processes.
• Cosmetic Actives Delivery: Employed in high-end cosmetic formulations to improve the skin penetration and stability of active ingredients.
• Diagnostic Reagents: Potential use in the development of lipid-based reagents for diagnostic assays and imaging techniques.
• Biochemical Research: A critical standard and intermediate for synthesizing more complex labeled or functionalized phospholipids for metabolic studies.

Quality Control

Our Stigmastanyl-Phosphorylcholine is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC for purity, NMR and IR for structural confirmation, and tests for residual solvents and heavy metals. We provide full traceability and Certificates of Analysis (COA) are available for all shipments, ensuring compliance with rigorous research and cGMP-grade material standards where applicable.

Storage

Preserve in a tightly closed container, protected from light. Store at -20°C or below under an inert atmosphere (e.g., nitrogen or argon) for long-term stability. This material is hygroscopic (moisture-sensitive) and should be handled in a dry environment. Allow the sealed container to reach room temperature before opening to prevent condensation.
