1-Hexadecanethiol is a chemical compound belonging to the group of thiols .

Extraction and presentation

1-Hexadecanethiol can be obtained by reacting 1-bromohexadecane with thiourea .

properties

1-Hexadecanethiol is a flammable colorless liquid with an unpleasant odor, which is practically insoluble in water.

use

1-Hexadecanethiol is used as a synthetic chemical. It is also used to make nanoparticles and hydrophobic self-assembling monolayers . The high affinity of the thiol group for elements of the copper group means that the thiols are spontaneously deposited in a highly ordered layer when a corresponding metal is exposed to a 1-hexadecanethiol solution
