<p>Scopine-2,2-dithienyl glycolate is a catalyst that belongs to the class of dithienyl glycolates. Scopine-2,2-dithienyl glycolate is used in the pharmaceutical industry as an average catalyst for reactions and can be used to recover dimethylbenzene. The method of detection for scopine-2,2-dithienyl glycolate is based on its ability to absorb light at a wavelength of 360 nm. The reaction solution must be monitored carefully during the synthetic process because it has been shown that it can react with water or air and form hydrogen sulfide gas. If this happens, the reaction solution will become cloudy or turbid. This product is a white crystalline solid that appears as tiny needles and has a melting point of 173 degrees Celsius (340 degrees Fahrenheit).</p>
