1-Hexadecanethiol is a chemical compound from the group of thiols. Its chemical formula is C
16H
34S.[1][2]
Synthesis[edit]
1-Hexadecanethiol can be obtained by reacting 1-bromohexadecane with thiourea.
Properties[edit]
1-Hexadecanethiol is a combustible colorless liquid with an unpleasant odor, which is practically insoluble in water.[3]
Applications[edit]
1-Hexadecanethiol is used as a synthesis chemical. The compound is also used for the production of nanoparticles and hydrophobic self-assembling monolayers. The high affinity of the thiol group to the elements of the copper group causes the thiols to spontaneously deposit in a high-order layer when a corresponding metal of a 1-hexadecanethiol solution is exposed.[4]
Toxicology and safety[edit]
The substance decomposes upon combustion with the formation of toxic gases, including sulfur oxides. It reacts violently with strong oxidizing agents, acids, reducing agents, and metals.

Well, that’s interesting to know that Psilotum nudum are known as whisk ferns. Psilotum nudum is the commoner species of the two. While the P. flaccidum is a rare species and is found in the tropical islands. Both the species are usually epiphytic in habit and grow upon tree ferns. These species may also be terrestrial and grow in humus or in the crevices of the rocks.
