The dimerization of alkanethiol mixtures (hexanethiol, octanethiol, and dodecanethiol) to form self-assembled monolayers (SAMs) from headspace on nanoporous gold surfaces was studied for the first time using gas chromatog. (GC/MS) and time-of-flight secondary ion mass spectrometry (TOF-SIMS). The nanoporous gold surfaces were obtained by an acidic etching of a 585-gold alloy. Field emission SEM (FE-SEM) was utilized to study the change of the surface geometry and porosity of the gold surfaces before and after etching. Alkanethiols were deposited from the vapor phase above the thiol solutions (headspace) on nanoporous gold plates and nanoporous gold solid-phase vmicroextn. (SPME) fibers. The nanoporous gold substrates were analyzed by TOF-SIMS and GC/MS, resp. The TOF-SIMS spectra exhibited various gold-sulfur ion clusters and specific peaks related to the adsorption of thiols such as deprotonated monomers, thiolate-Au, dimers (e.g., dialkyl sulfides-Au and dialkyl disulfides-Au). The GC/MS anal. of headspace extractions of alkanethiol mixtures by nanoporous gold SPME fibers showed a high extraction efficiency of alkanethiol, dialkyl sulfide, and dialkyl disulfide when compared with the com. SPME fibers (DVB-CAR-PDMS and CAR-PDMS). Different GC/MS optimization factors were studied including the extraction time and desorption temperature This study involved multiple reactions and reactants, such as 2,5-Dimethylthiophene (cas: 638-02-8Computed Properties of C6H8S).
2,5-Dimethylthiophene (cas: 638-02-8) belongs to benzothiophene derivatives. Benzothiophene scaffolds are of great importance due to its increased presence in bioactive molecules. It is found within the chemical structures of pharmaceutical drugs such as raloxifene, zileuton, and sertaconazole, and also BTCP.Computed Properties of C6H8S
