Application

Chloroform was used in the process for isolation of RNA from yeast.
It may be used in the following processes:
  • Synthesis of colloidal hydrophobic CdSe core nanocrystals (quantum dots).
  • Preparing phospholipid solutions.
  • As a solvent in the photolysis reaction of ruthenium complexes.
  • Solvent for recrystallization.
  • Reference compound to detect the presence of chloroform in tobacco smokes.
  • Extractant in solvent extraction process.
