CAS:5-Methylbenzo[b]thiophene is an inorganic chemical that has been found to be toxic to cells. The cytotoxicity of 5-methylbenzo[b]thiophene is strain-dependent and was observed in wild-type cells, but not in a strain with a mutation in the sulfite reductase gene. This chemical also affects the concentration of Ca2+ ions and carbon sources, which are important for cellular metabolism. The linear regression analysis suggests that ionizable groups may be responsible for this toxicity. Acute toxicities were seen at high concentrations and include oxidative stress, cell death, and DNA damage.Formula:C9H8SPurity:Min. 95%Molecular weight:148.23 g/mol5-(2-Chlorophenyl)thiophene-2-carboxylic acid

Discontinued productEthyl 2-methylthiophene-3-carboxylate
CAS:Ethyl 2-methylthiophene-3-carboxylate is an intermediate in the synthesis of a variety of organic compounds, including fluoroalcohols and pharmaceuticals. The synthesis is based on the Wittig reaction, which involves the formation of a wittig reagent from a magnesium halide and a carboxylic acid chloride. This reagent reacts with an aromatic compound such as thiophene to form an alkyl group at the α position. The alkylation proceeds intramolecularly to form ethyl 2-methylthiophene-3-carboxylate without any need for an external base. Ethyl 2-methylthiophene-3-carboxylate can be obtained through a scalable, efficient method that uses Grignard reagents as starting materials.Formula:C8H10O2SPurity:Min. 95%Molecular weight:170.23 g/molRef: 3D-FE139396

CAS:2,5-Dithiophen-2-yl-thieno[3,2-b]thiophene (DTTS) is an organic semiconductor that has potential applications in polymer solar cells. The polymerization of DTTS can be achieved through a number of methods including thermal evaporation or solution-based processing. This polymerization produces a low molecular weight material with an interchain distance of approximately 2.5 Å and a redox potential approximately 0.5 V more positive than that of the parent compound. The photovoltaic properties of DTTS have been studied by systematically varying the methyl ester substituent at the para position and determining the effect on the carrier transport, kinetic stability, and optical absorption spectra. These studies show that when this substituent is methylated, DTTS has increased photovoltaic efficiency due to a reduced electron transport rate between chains and improved charge transfer kinetics.Formula:C14H8S4Purity:Min. 95%Molecular weight:304.48 g/molRef: 3D-FD156502

CAS:2-Methoxythiophene is a molecule that belongs to the class of aromatic heterocycles. It is an intermediate in the synthesis of other molecules, such as carbonyl compounds, which are important for cancer diagnosis. 2-Methoxythiophene has been used to produce acetylated derivatives and then analyzed by solid phase microextraction followed by gas chromatography and mass spectrometry. The chloride ion can be detected by gas chromatography with flame ionization detection. 2-Methoxythiophene can also be used to detect cancer cells in urine samples because it reacts with nucleophilic groups on the cancer cells and cleaves bonds between chloride ions and nucleophilic groups on the cell surface. This reaction produces hydrogen chloride, which is detectable by gas chromatography.Formula:C5H6OSPurity:Min. 95%Molecular weight:114.17 g/molRef: 3D-FM147337
