| Hazard Information | Back Directory | [Reactivity Profile]
1-OCTADECANETHIOL is non-flammable but combustible (Flash point >100°F and <140°F). Incompatible with oxidizing agents, strong acids and strong bases, alkali metals, and nitric acid. Can react with water, steam or acids to produce toxic and flammable vapors. Reacts violently with powerful oxidizing agents such as calcium hypochlorite(Ca(OCl)2) to generate SOx. Reacts with hydrides to form flammable H2 gas; reacts with halogenated hydrocarbons to yield HX. Reacts exothermically with aldehydes. Emits toxic compounds of sulfur when when heated to decomposition. | [Chemical Properties]
white powder with an extremely unpleasant smell | [General Description]
1-Octadecanethiol (ODT) is a water soluble sulfur compound with an 18 carbon alkyl chain, which forms a strong hydrophobic assembly with transition metals, like gold .It forms self-assembled monolayers (SAMs) on the surface of such transition metals. The thiol membrane when covalently bonded with the surface of the metal electrode, it shows electrostriction phenomenon leading to variation in capacitance.ODT SAMs have a hydrophobic surface with contact angle of 102oC. | [Hazard]
Strong irritant. | [Flammability and Explosibility]
