Tert-butanol application and related research progress in biomedicine

Tert-butanol is an organic solvent, widely used in the medical field and chemical industry. It could be characterized by high crystallization temperature and vapor pressure. It could be easily sublimed and removed during the freeze-drying process. This review mainly describes the use of tert-butanol in the lyophilized formulations of poorly soluble drugs, the lyophilization solvent of porous structure productions, and as an ice crystal growth guider. In addition, the application of tert-butanol in nano drugs and aerogels has also been reviewed, as well as the current research progress in its quality and safety.
