Description

Application

• 2-Propanol in solvent applications: 2-propanol is used as a solvent in swelling and delamination of inorganic homoionic montmorillonite clay. The study emphasized its utility in water-polar organic mixed solvents, showcasing its importance in industrial processes requiring high-purity solvents (Nakato et al., 2024).


• 2-Propanol in chromatography: 2-Propanol is used in a static headspace gas chromatography method for quantitating residual solvents in nanoformulations. This reflects its critical role in analytical techniques like chromatography where reagent grade solvents are essential for accurate and reliable results (Kattel and Clogston, 2024).


• 2-Propanol in biochemistry research: used as a solvent in the amination of heterocycles under acidic conditions. This study points to its utility as an IPA solvent in biochemistry research, enabling innovative approaches to pharmaceutical compound development (Yasuda et al., 2024).
