18-Methyleicosanoic acid

Description:
18-Methyleicosanoic acid, also known as 18-methyl-20-carbon fatty acid, is a branched-chain fatty acid characterized by its long carbon chain and a methyl group at the 18th carbon position. This compound has a molecular formula of C21H42O2 and features a carboxylic acid functional group, which imparts typical acid properties such as the ability to donate protons in solution. It is a solid at room temperature and is insoluble in water but soluble in organic solvents, reflecting its hydrophobic nature. The presence of the methyl branch affects its melting point and physical properties compared to straight-chain fatty acids, often resulting in lower melting points. 18-Methyleicosanoic acid is of interest in various fields, including biochemistry and materials science, due to its unique structural characteristics that can influence the properties of lipids and polymers. Additionally, it can be used in the synthesis of surfactants and as a potential additive in various industrial applications.
