Application
Thiodiglycol (2,2′-Thiodiethanol, TDE) is used as a solvent and as a refractive index modifying component of mounting media for microscopy. Thiodiglycol may also be used as a charge modifier for procedures such as electrospray ionization mass spectrometry. Thiodiglycol is used as a reference material in the evaluation of the degradation of sulfur mustard gas by bacteria.
