General description

Chloroform, a halogenated hydrocarbon, is widely employed as a solvent. Its photochemical degradation has been investigated in the presence of TiO2 aqueous suspensions (wavelength range of 310-380nm).

Application

Chloroform may be employed as a solvent for the following studies:
  • Extraction of RNA from plant cells.
  • Preparation of dioleoylphosphatidylcholine (DOPC) solution.
  • Dissolution of 1,2-distearoyl-sn-glycero-3-phosphocholine (DSPC).
It may be employed in a rapid quantitative method for the release of periplasmic proteins from bacterial strains.
Chloroform may be used as a solvent to enhance the enantioselectivity of secondary alcohols formed by the borohydride reduction of carbonyl compounds in the presence of optically active ketoiminatocobalt complexes.
