Comm., 48, 10434 (2012); Freitas, V. et al.: Struct. Chem., 24, 661 (2013);<br></p>

<p>Applications 4-Chlorobenzenethiol is a reagent used in the synthesis of small-molecule inhibitors of the protein geranylgeranyltransferase Type I (GGTase-I), acting as anti-tumor agents. Also is used in the synthesis of β-sulfanyl carbonyl compounds via Michael addition.<br>References Ranu, B. et al.: Tetrahedron, 60, 4183 (2004); J. Med. Chem., 43, 2310 (2000);<br></p>

<p>Applications Intermediate in the preparation of Rotigotine<br>References Janssens, F., et al.: J. Med. Chem., 29, 2290 (1986),<br></p>

<p>Applications N-(4-Chlorobenzyl)-1-(5-nitrothiophen-2-yl)methanamine is an analogue of GSK 4112 (G797700) which is a synthetic ligand for REV-ERBα, a member of the nuclear receptor superfamily that functions as a receptor for the porphoryin heme. GSK 4112 mimics the action of heme acting as agonist and suppresses the expression of REV-ERBα target genes involved in gluconeogenesis.<br>References Kojetin, D. et al.: ACS Chem. Biol., 6, 131 (2011); Grant, D. et al.: ACS Chem. Biol., 5, 925 (2010)<br></p>

<p>Applications 5-(2-Sulfanylidene-3H-1,3-thiazol-4-yl)thiophene-2-carboxamide is a compound involved in the multi-step synthesis of arotinolol hydrochloride.<br>References Liu, H., et al.: Zhongguo Yiyao Gongye Zazhi, 42, 641-644 (2011)<br></p>

<p>Applications 2,4,7-Trimethyldibenzothiophene is found in crude oil and can be used to determine the maturity of the oil.<br>References Hegazi, A.H., et. al.: Polycycl. Aromat. Comp., 24, 123 (2004)<br></p>

<p>Applications 5-Bromo-2-thiophenecarboxaldehyde is used in biological studies as anti-inflammatory and anti-tumor activity of the marine mangrove Rhizophora apiculata.<br>References Prabhu, V.V., et al.: J. Immunotoxicol., 9, 341 (2012);<br></p>

<p>Applications 3-Acetyl-2,5-dimethylthiophene Standard (cas# 2530-10-1) is a useful research chemical.<br></p>

<p>Applications Dibenzothiophene is commonly used in microbial studies as a sole, organic sulfur and carbon source for growth. Research concerning the biodegradation of dibenzothiophene by different types of bacteria is a currently being carried out, as these bacteria have the ability to breakdown other harmful polycyclic hydrocarbons (PAH) as well. This may prove to be a very practical method in removing PAH’s from soils, sludge and crude oils.<br> Not a dangerous good if item is equal to or less than 1g/ml and there is less than 100g/ml in the package<br>References Bastiaens, L., et al.: Appl. Environ. Microb., 66, 1834 (2000); Gunam, I., et al.: J. Microbiol. Biotechn., 23, 473 (2013); Omori, T., et al.: Appl. Environ. Microb., 58, 911 (1992)<br></p>

<p>Applications Benzo[b]thiophene has application in organic as well as pharmaceutical industry as a component in the synthesis of Raloxifene, a breast cancer therapeutic, or hydrodesulfurization reactions.<br>References Buccella, D. et al.: J. Am. Chem. Soc., 130, 16187 (2008); Gennari, L. et al.: Exp. Opin. Drug Saftey, 7, 259 (2008);<br></p>

<p>Thiophene-2-glyoxylic acid is a reactive metabolite of thiophene that is formed from the environmental degradation of this compound. Thiophene-2-glyoxylic acid reacts with halides to form an electrophilic intermediate. This intermediate can react with a variety of nucleophiles, including the drug metabolites, leading to the formation of new compounds. Thiophene-2-glyoxylic acid has been shown to enhance the fluorescence properties of some organic compounds. It also has been shown to inhibit the metabolism of some drugs that are conjugated with acids and can be detected in plasma by mass spectrometry.</p>

<p>2-Amino-4,5,6,7-tetrahydro-1-benzothiophene-3-carboxamide is an anticancer agent that inhibits the synthesis of proteins required for cell division. It has been shown to have anticancer activity and efficacy in vitro studies against human cancer cells, such as HCT116. This compound also induces apoptosis in infected cells by binding to viral particles and inducing the release of chloride ions. 2-Amino-4,5,6,7-tetrahydro-1-benzothiophene-3-carboxamide has been found to be effective against influenza virus and particle production by inhibiting neuraminidase activity.</p>
