Bismuth organic thiols

WebThiols (also called mercaptans) are organic molecules that contain a sulfhydryl (–SH) group. These compounds, which are sulfur analogs of alcohols, have the general formula R–SH. Methanethiol (also called methyl mercaptan), has the formula CH 3 SH. Ethanethiol (ethyl mercaptan) is the most common odorant for liquid propane (LP) gas.
