3-Ethylthiophene (cas: 1795-01-3) belongs to benzothiophene derivatives. Functionalized benzothiophenes are important constructs found in molecules with wide ranging biological activity and in organic materials. Its aromaticity makes it relatively stable, although as a heterocycle, it has reactive sites which allow for functionalization.Recommanded Product: 1795-01-3

Multidimensional gas chromatography in combination with accurate mass, tandem mass spectrometry, and element-specific detection for identification of sulfur compounds in tobacco smoke was written by Ochiai, Nobuo;Mitsui, Kazuhisa;Sasamoto, Kikuo;Yoshimura, Yuta;David, Frank;Sandra, Pat. And the article was included in Journal of Chromatography A in 2014.Recommanded Product: 1795-01-3 This article mentions the following:

A method is developed for identification of sulfur compounds in tobacco smoke extract The method is based on large volume injection (LVI) of 10 μL of tobacco smoke extract followed by selectable one-dimensional (1D) or two-dimensional (2D) gas chromatog. (GC) coupled to a hybrid quadrupole time-of-flight mass spectrometer (Q-TOF-MS) using electron ionization (EI) and pos. chem. ionization (PCI), with parallel sulfur chemiluminescence detection (SCD). In order to identify each individual sulfur compound, sequential heart-cuts of 28 sulfur fractions from 1D GC to 2D GC were performed with the three MS detection modes (SCD/EI-TOF-MS, SCD/PCI-TOF-MS, and SCD/PCI-Q-TOF-MS). Thirty sulfur compounds were pos. identified by MS library search, linear retention indexes (LRI), mol. mass determination using PCI accurate mass spectra, formula calculation using EI and PCI accurate mass spectra, and structure elucidation using collision activated dissociation (CAD) of the protonated mol. Addnl., 11 mol. formulas were obtained for unknown sulfur compounds The determined values of the identified and unknown sulfur compounds were in the range of 10-740 ng mg total particulate matter (TPM) (RSD: 1.2-12%, n = 3). In the experiment, the researchers used many compounds, for example, 3-Ethylthiophene (cas: 1795-01-3Recommanded Product: 1795-01-3).
