Hexadecanethioic acid

Description:

Hexadecanethioic acid, also known as hexadecanethiol or 1-hexadecanethiol, is a long-chain aliphatic thiol with the chemical formula C16H34S. It features a straight-chain structure with a thiol (-SH) functional group at one end, which imparts unique properties to the molecule. This compound is typically a colorless to pale yellow liquid with a characteristic odor. Hexadecanethioic acid is insoluble in water but soluble in organic solvents, making it useful in various applications, including as a surfactant, lubricant, and in the synthesis of thiol-functionalized materials. Its long hydrophobic carbon chain contributes to its surface-active properties, allowing it to form self-assembled monolayers on metal surfaces, which is valuable in nanotechnology and materials science. Additionally, due to the presence of the thiol group, it can participate in various chemical reactions, including oxidation and metal coordination, further expanding its utility in organic synthesis and catalysis. Safety precautions should be taken when handling this compound, as thiols can be toxic and have strong odors.
