Acetonitrile

Acetonitrile (CH₃CN) is a polar aprotic solvent and the simplest organic nitrile, valued for its high dielectric constant, low viscosity, and complete miscibility with water and most organic solvents. It is extensively used in high-performance liquid chromatography (HPLC), organic synthesis, and as a solvent in battery electrolytes and pharmaceutical production. Toxic and flammable, acetonitrile requires careful handling under well-ventilated conditions, with appropriate protective equipment and fire safety measures.

Acetonitrile, Uvasol® for spectroscopy, Supelco®

Supplier: MilliporeSigma

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.

Acetonitrile, LiChrosolv®, Isocratic Grade for liquid chromatography, Supelco®

Supplier: MilliporeSigma

Offering a high degree of UV transmittance, low particle count, low acidity and alkalinity, and low evaporation residue level, LiChrosolv® solvents are ideal for reproducible separations. They are produced from specially selected raw materials, and undergo a number of purification steps prior to final packaging. Since separations are normally carried out under gradient conditions in analytical HPLC, Merck Millipore offer solvents in ’gradient grade’ as well as ’isocratic grade’. This enables you to minimise the gradient effect of the solvent involved.
