    Description

    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).[1]

    Application

    Chloroform may be employed as a solvent for the following studies:
    • Extraction of RNA from plant cells.[3]
    • Preparation of dioleoylphosphatidylcholine (DOPC) solution.[4]
    • Dissolution of 1,2-distearoyl-sn-glycero-3-phosphocholine (DSPC).[5]
    It may be employed in a rapid quantitative method for the release of periplasmic proteins from bacterial strains.[2]

    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.[6]
