<p>2,6-Dimethylthiophenol is a structural analog of the natural product sumatrana. It has been shown to be an effective catalyst for the cleavage of carbon-carbon bonds in organic molecules and fatty acids. 2,6-Dimethylthiophenol is unique because it contains two sulfur atoms that are part of a thiolate group, which can easily be oxidized to a sulfoxide or sulfone. This property makes 2,6-dimethylthiophenol an excellent reductant in reactions that require a metallacycle intermediate. The reactivity of this molecule is also influenced by its redox potential and the presence of nitrogen atoms. 2,6-Dimethylthiophenol was synthesized and studied using model compounds, yielding reaction yields as high as 98%.</p>

<p>3-Tetradecylthiophene is a colorless liquid with a refractive index of 1.547, which has an onset of 10-20°C and a dilution of 0.01%. The compound has an absorption spectrum in the region of 230-390 nm, with a maximum at 340 nm and a quantum efficiency of 0.2%. 3-Tetradecylthiophene is used as a monomer for the preparation of polymer films and coatings. It can be copolymerized with other materials to produce polymers that are optically active due to their shift in position on the visible light spectrum.</p>
