General description

Chloroform is widely used as an industrial solvent, aerosol propellant and as a preservative in concentrations between 0.1 and 0.5 percent in aqueous pharmaceutical preparations. It is a human carcinogen with cardiotoxic and hepatotoxic effects and is also known to cause skin infections.

Application

Chloroform may be used as an analytical standard for the determination of the analyte in aqueous pharmaceutical formulations by chromatography and drinking water samples by spectrofluorimetry.
Refer to the product′s Certificate of Analysis for more information on a suitable instrument technique. Contact Technical Service for further support.

Solution-processed organic photovoltaic cells (OPVs) hold great promise to enable roll-to-roll printing of environmentally friendly, mechanically flexible and cost-effective photovoltaic devices. Nevertheless, many high-performing systems show best power conversion efficiencies (PCEs) with a thin active layer (thickness is ~100 nm) that
