Tetrachloroethylene for spectroscopy Uvasol®. CAS 127-18-4, EC Number 204-825-9, chemical formula Cl₂CCCl₂
Accurate analytic results in UV/VIS and infrared spectroscopy depend on the use of very pure solvents for sample preparation. The Uvasol® solvents range has been specially designed for spectroscopy and other applications requiring solvents of the highest spectral purity. The refinement process allows a greater degree of security in applications and avoids misinterpretation of analytical results caused by traces of UV, IR and fluorescence contamination. Uvasol® solvents offer best UV transmittance. In all specifications the minimum transmittance for 5 typical wavelengths are identified. Furthermore the transmittance is specified in accordance with Reag. Ph Eur and ACS.
Tetrachloroethylene or perchloroethylene is a colorless volatile nonflammable liquid with an ether-like odor that may emit toxic fumes of phosgene when exposed to sunlight or heat. Tetrachloroethylene is used as a cleaning solvent in dry cleaning and textile processing in the manufacture of fluorocarbons as a lab solvent degreaser and chemical intermediate.
