WebPeptide coupling reagents are more than fancy dehydrating reagents [82], and there is a wide range of costs.Some commercially available reagents shown in Table 4.5 are ranked by the cost per mol relative to thionyl chloride, along with some exemplary references. (Thionyl chloride was selected as the least expensive reagent, for the formation of acid chlorides. Thionyl chloride is a component of lithium–thionyl chloride batteries, where it acts as the positive electrode (in batteries: cathode) with lithium forming the negative electrode (anode); the electrolyte is typically lithium tetrachloroaluminate. The overall discharge reaction is as follows: $${\displaystyle {\ce {4 Li + 2 … See more Thionyl chloride is an inorganic compound with the chemical formula SOCl2.
