LiC18

LiC18, also known as lithium octadecyl sulfate, is a cationic surfactant commonly used in various industrial and scientific applications. It is a member of the quaternary ammonium compound family, characterized by its long alkyl chain, which imparts unique properties to the surfactant. The "18" in LiC18 refers to the length of the alkyl chain, which contains 18 carbon atoms.

LiC18 is highly soluble in water and organic solvents, making it versatile for use in a wide range of applications. It is often employed as a wetting agent, emulsifier, and dispersant in formulations such as paints, coatings, and inks. Its cationic nature allows it to interact with negatively charged surfaces, enhancing adhesion and improving the stability of emulsions.

In the field of analytical chemistry, LiC18 is used as a stationary phase in high-performance liquid chromatography (HPLC) for the separation of organic compounds. Its hydrophobic nature enables the retention of non-polar analytes, facilitating their separation from more polar compounds.

LiC18 is also utilized in the preparation of solid-phase extraction (SPE) cartridges for the purification and concentration of analytes from complex matrices. Its ability to bind to both polar and non-polar compounds makes it a valuable tool in sample preparation.

Despite its numerous applications, LiC18 should be handled with care due to its potential toxicity. It is important to follow proper safety guidelines when working with this compound to minimize the risk of exposure.
