Coal tar is a complex mixture of organic compounds obtained from the thermal treatment of coal; it contains several different chem. classes of compounds, such as polycyclic aromatic hydrocarbons, phenols and different heterocyclic compounds including sulfur derivatives In the present research, a target anal. was carried out for the characterization of fourteen different classes of organic sulfur compounds in coal tar by using cryogenically-modulated (CM) comprehensive two-dimensional gas chromatog.-high resolution time-of-flight mass spectrometry (GCxGC-HR ToFMS) with the support of target analyte finding, a specific software function. Furthermore, absolute quantification data were obtained by using eight pure standard sulfur compounds, and 1-fluoronaphthalene as internal standard Several figures-of-merit of the proposed method were measured (linearity, intra-day precision, limits of detection and quantification). Finally, the overall anal. performance of CM GCxGC-HR ToFMS was evaluated, in relation to MS similarities, mass accuracies, second-dimension peak widths, peak capacity and tailing factors. The approach proved itself as being a powerful anal. platform, benefiting from the high sensitivity, selectivity and resolving power, of both the GC and MS sides. 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. Benzothiophenes are valuable heterocycles that are widely used in medicines, agrochemicals, and materials science. Due to its aromaticity, thiophenes do not exhibit the same properties as conventional thioethers.Computed Properties of C6H8S
