Description

Stearoylcholine Iodide is a quaternary ammonium salt with a long-chain fatty acyl group, combining surfactant and cholinergic properties. This unique structure makes it a valuable intermediate and functional agent in advanced chemical synthesis and formulation. It is particularly relevant for researchers and manufacturers in the pharmaceutical, cosmetic, and specialty chemical industries seeking to develop or enhance products with specific surface-active or bioactive characteristics.

Application

• Pharmaceutical Research: Used as a key intermediate in the synthesis of novel cholinergic compounds and prodrugs.
• Cosmetic Formulations: Acts as a cationic surfactant and emulsifier in hair conditioners, skin creams, and other personal care products.
• Biochemical Studies: Serves as a substrate or inhibitor in enzymatic research related to choline metabolism and acetylcholinesterase activity.
• Surface Science: Employed in the preparation of Langmuir-Blodgett films and other monolayer studies due to its amphiphilic nature.
• Specialty Chemical Synthesis: A building block for creating ionic liquids, phase-transfer catalysts, and other functional materials.

Quality Control

Our Stearoylcholine Iodide is produced under a rigorous quality management system. Each batch undergoes comprehensive analytical testing to ensure identity, purity, and consistency. A detailed Certificate of Analysis (COA) is provided with every shipment, documenting key parameters such as assay, melting point, and impurity profiles. We adhere to cGMP principles where applicable to support our clients in regulated industries.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area 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 degradation from atmospheric moisture.
