<p>Applications 2-Chlorothiophene (cas# 96-43-5) is a useful research chemical.<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></p>

<p>Applications 2-Methyldibenzothiophene, is an alkyldibenzothiophene present in crude oil. 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 PAH’s as well. This may be used in removing spilled oil from marine and terrestrial environments.<br>References Boberg, F., et al.: Erdoel &amp; Kohle, Erdgas, Petrochemie, 47, 187 (1994); Tanaka, Y., et al.: Applied Microbiology and Biotech., 59 (2), 325 (2002); Prince, R., Spill Sci.
