Product Description

Isopropanol is a polar organic solvent that is widely used in chemistry, biochemistry and molecular biology. Industrial applications include its use in antifreezes, quick-drying oils, and quick-drying inks, and as a solvent for gums, shellac, and essential oils.1 Isopropanol has been utilized as a solvent in the synthesis of solid phase acylating agents.2

Protocols for the use of isopropanol in DNA precipitation from mammalian tissue, ethidium bromide extraction from DNA samples, and RNA isolation from cells and tissues have been reported.3 Isopropanol has been utilized in protein crystallization.4,5,6 The use of isopropanol to isolate retinoids from biological matrices for HPLC and HPLC-MS analysis has been reported.7,8 A mathematical analysis of isopropanol and other organic solvents to examine the selectivity of stationary phases and organic modifiers in reversephase HPLC systems has been published.9
