1,1'-Thiocarbonyldiimidazole is used as a reagent for the deoxygenation of alcohols with tributyltin hydride and diols with lithium aluminum hydride. It is also used to deoxygenate carboxylic monosaccharide analogues. Further, it is a useful reagent involved in biochemical synthesis. In addition to this, it is used to prepare 1-[bis-(4-methoxy-phenyl)-methyl]-1H-imidazole by reacting with 4,4'-dimethoxy-benzhydrol.
This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.
