| Application: | Toluene may be used for decontamination of microbial cultures and lyse bacterial cells in bacterial enzyme assays. It may be used as a solvent for the preparation of 4-arm polylactide-based (PLA) star oligomer. It was used for the activation of glass slides, for in vitro test system for allergy diagnosis. |
| General description: | Toluene, a benzene analog, is widely employed as an organic solvent. It has been reported to be a biotoxic solvent (toxic to many microorganisms at 0.1% v/v concentrations). Its anaerobic biodegradation to CO2, by the denitrifying bacterium Thauera arornatica has been reported. It forms syndiotactic polystyrene-toluene molecular compound. Crystal structure of this molecular compound has been investigated by X-ray diffraction studies. |
