Octadecyl sulfide, with the CAS number 1844-09-3, is an organic compound characterized by a long hydrophobic alkyl chain consisting of 18 carbon atoms, attached to a sulfur atom. This structure imparts unique properties, making it a non-polar, hydrophobic substance. Octadecyl sulfide is typically a colorless to pale yellow liquid or solid, depending on temperature and purity. It is insoluble in water but soluble in organic solvents, which is characteristic of long-chain alkyl sulfides. The compound is often used in various applications, including as a surfactant, lubricant, or in the formulation of specialty chemicals. Its hydrophobic nature allows it to interact favorably with other non-polar substances, making it useful in enhancing the stability and performance of formulations in industrial and research settings. Additionally, octadecyl sulfide can participate in chemical reactions typical of sulfides, such as oxidation or substitution reactions, which can be leveraged in synthetic organic chemistry. Safety data should be consulted for handling and exposure guidelines, as with all chemical substances.
