Description

18-Mercaptooctadecanoic acid features a long aliphatic chain terminating in both a thiol and a carboxylic acid group, enabling dual functionality for surface anchoring and bioconjugation. The thiol moiety facilitates strong covalent attachment to gold surfaces, while the terminal carboxyl group supports further derivatization via amide or ester linkages. This amphiphilic structure promotes stable monolayer formation under standard conditions.

Application

18-Mercaptooctadecanoic acid serves as a versatile bifunctional building block for thiol-terminated lipid and polymer synthesis. Its long aliphatic chain provides robust hydrophobic character, while the terminal thiol group enables reliable conjugation via gold-thiolate or maleimide chemistry. The carboxylic acid functionality facilitates amide coupling or esterification, enabling modular assembly of functionalized surfaces, drug delivery systems, and bioconjugates. Bench-stable and readily purified by recrystallization, it supports scalable synthesis in medicinal chemistry and materials science workflows.
