Octacosane
Octacosane (CAS: 630-02-4), with the linear formula CH3(CH2)26CH3 and a molecular weight of 394.76 g/mol, is a long-chain alkane. It is a saturated hydrocarbon characterised by its waxy solid form at room temperature. Octacosane is primarily utilised as a chemical building block in synthesis and finds applications in areas such as cell biology and nutrition research, often occurring naturally in plant cuticular waxes.

Chemical Synthesis
As a saturated hydrocarbon with a 28-carbon chain, Octacosane serves as a valuable building block in organic synthesis. Its long alkyl chain can be functionalised or incorporated into larger molecular structures, contributing specific lipophilic properties.
Cell Biology Research
Octacosane is studied for its presence in biological membranes and its potential roles in cellular processes. Its lipophilic nature makes it relevant for investigations into lipid metabolism and membrane structure.
Nutrition Research
This long-chain alkane is a component of certain natural sources, including plant waxes. Research into its dietary presence and metabolic fate contributes to understanding lipid nutrition and the role of long-chain hydrocarbons in biological systems.
Analytical Standards
Due to its defined structure and purity, Octacosane can be used as an analytical standard in chromatography and other analytical techniques for identifying and quantifying long-chain alkanes in complex mixtures.
