General description

2-propanol, also known as isopropanol or Isopropyl alcohol, is a 70% solution in water. It 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

Packaging

500, 6×500 mL in glass bottle
1, 6×1, 2.5, 4, 4×4 L in glass bottle
4×4 L in poly bottle
18, 200 L in steel drum

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.
