Acetonitrile is a highly polar, volatile organic compound used as a solvent in many industrial applications.
Acetonitrile is a liquid with an etherlike odor. It is a highly polar, volatile solvent used in many different industrial applications. It is widely used in the pharmaceutical, photographic, chemical, and analytical industries. It is useful
0.33 mmol) inacetonitrile (10 ml) at room temperature, and the resulting mixture was stirredat room temperature for 2 h. Et 3 N (0.12 ml) was added and themixture was stirred at room temperature for 15 min. The solvents were removedin vacuo, and the residue was extracted with ethyl ace...
To a solution of6-methoxy-3-methylindole(5.0 g,31 mmol) in distilled acetonitrile (150 mL) were added di- tert butyl dicarbonate(7.44 g, 34.1 mmol) andDMAP (0.195 g, 1.6 mmol).The reaction mixture was stirred at rt for 12 h. The solvent was removed underreduced pressure. The residue ...
The solvent, which remains liquid to low temperatures, is a binary or higher order system comprising diethyl carbonate and one or more of propylene carbonate, ethylene carbonate, dimethyl carbonate, dipropylcarbonate, dimethylsulfoxide, acetonitrile, dimethoxyethane, tetrahydrofuran, n-methyl-2-pyrrolidone...
The proposed framework is demonstrated on 26 organic solvents. Results show that simple alcohols (methanol, ethanol) or alkanes (heptane, hexane) are environmentally preferable solvents, whereas the use of dioxane, acetonitrile, acids, formaldehyde, and tetrahydrofuran is not recommendable from an ...
The solvent system consisted of 0.1% (v/v) trifluoroacetic acid in water (A) and 0.1% (v/v) trifluoroacetic acid in acetonitrile (B), and the sample was eluted with a linear gradient of 0–16% B over 30 min, with a flow rate of 1 mL/min. The products were detected by UV ...
(0.06% formic acid in acetonitrile) in 15 min. About 2.5 μl of the sample was injected into the column with an optimal flow rate of 400 µl/min. A diode array detector (UV/Vis DAD) was attached to the column, and the wavelengths of 230, 260, 280, 360, and 435 nm were ...
Subsequently, 400 μl of 155 mM ammonium bicarbonate in water, 300 μl of acetonitrile, and 100 μl of isopropanol (LC-MS grade) were added. The Eppendorf safe-lock tubes were briefly vortexed in the cold room, then sonicated in an ice bath, and incubated on a shaker (1600 rpm) for...
