1-Octadecanol is a fatty alcohol that finds extensive use in of material science and organic chemistry. Its long hydrocarbon chain renders it a useful compound for studying lipid bilayers and the properties of cell membrane models, thereby providing insights into membrane dynamics and permeability. In the area of green chemistry, 1-Octadecanol is of interest as a renewable feedstock for the production of biodegradable surfactants and emulsifiers. Its solid-state behavior and phase-transition properties at the boundary of liquid and solid states are further investigated to inform the design of phase-change materials (PCMs) for thermal energy storage applications. Due to its amphiphilic nature, it serves as a stabilizing agent in the formulation of various nanostructured systems, such as vesicles or liposomes, for controlled delivery and release studies.
