Tetrahydrothiophene is a sulfur-containing saturated heterocyclic compound obtained by catalytic hydrogenation of thiophene. After thiophene is reduced to tetrahydrothiophene, it no longer has a conjugated system and aromaticity. Therefore, tetrahydrothiophene shows the properties of general thioethers. Easily oxidized to sulfoxides and sulfones. Tetrahydrothiophene can be used as a raw material for the production of pharmaceuticals, pesticides and photochemicals.
Silanes are a series of silicon substitutes for carbon alkanes, which consisting of multiple silicon atoms linked to each other as the main chain and hydrogen atoms or other chemical elements linked with the main chain. Silanes are versatile chemicals used in the modification of SPR sensor surfaces. In particular, the silane molecules, such as 3-mercaptopropyl trimethoxy silane, are convenient for use as linkers in surface modification of SPR sensors.
