General description

2-propanol, also known as isopropanol or Isopropyl alcohol, is a secondary alcohol, colorless liquid, widely used as a solvent and intermediate in organic syntheses, miscible in solvents such as water, ethanol, ether, ethyl acetate, THF, and chloroform.

Application

Isopropanol can be used in many different applications due to its properties.
  • Solvent in organic synthesis
  • Chemical intermediate
  • Disinfectant
  • Antibacterial
  • Sample preservative

Features and Benefits

ACS solvents meet or exceed the high standards of the American Chemical Society (ACS) ,with test specifications that are specialized to every compound. According to the American Chemical Society, ACS reagent grade implies that it is a substance of sufficient purity to be used in most chemical analyses or reactions.
