Applications

1-Hexadecanethiol is used in the study of nanoparticles and self-assembled monolayers. It is also used to prepare thiol-functionalized 1.5 nm gold nanoparticles via a ligand exchange process with triphenylphosphine-stabilized nanoparticles and in the formation of hydrophobic self-assembled monolayers (SAMs). Due to the length of the alkane chain, the resulting monolayer is highly ordered. 1-Hexadecanethiol is also employed in different fields such as biomedicine, chemical industry, also used in electroplating industry and chemical auxiliaries.

Notes

Store in cool place. Keep container tightly closed in a dry and well-ventilated place. Containers which are opened must be carefully resealed and kept upright to prevent leakage. Store under inert gas. It is sensitive to air. Incompatible with oxidizing agents.
