Restek Corporation, U.S., 110 Benner Circle, Bellefonte, PA 16823Copyright © 2021 Restek Corporation. In general, using LC grade acetonitrile is the safest choice. Acetonitrile as a solvent used in liquid chromatography/mass spectrometry (LC/MS) of peptides and proteins is relatively toxic compared to alternatives like methanol and acetone. In a hurry? Click to view available options. The three-component mobile phase, methanol-acetonitrile-water, has been frequently used for the separation of natural products in complicated herbal extracts by reversed-phase liquid chromatography, especially when two-component solvent systems do not work. Shop a large selection of Application Specific Acetonitrile products and learn more about Acetonitrile, LC-MS Grade For Liquid Chromatography- Mass Spectrometry, OmniSolv In consequence of the decreasing demand for acrylonitrile due to the financial crisis, a worldwide shortage of acetonitrile is observed. Methanol and acetonitrile are commonly used as organic components of the mobile phases for a number of pre- ... phase extraction and capillary electrophoresis as well as planar and column chromatography.5 It is noteworthy that both molecules weakly interact with the internal cavities of common mobile-phase macrocyclic additives, such cyclodextrins. The calibration curve went great for the ethanol but we are having too much trouble with the acetonitrile repeatability.

We can help improve your knowledge in key areas such as understanding selectivity and method development. Baker®. 16th Feb, 2015. Chromatography Knowledge Centre. Hi, In our laboratory we are trying to detect acetonitrile and ethanol in a water solution and we were using methanol as internal standard. Thanks to the development of new sorbents and supports, as well as increasing instrumentation and automation, TLC has become a versatile separation method. Acetonitrile. In this work, acetone was substituted for acetonitrile in the separation of a peptide mixture by reversed-phase high-performance liquid chromatography (RP-HPLC) and in the positive electrospray ionization mass spectrometry (ESI-MS) of individual peptides.

Acetonitrile for chromatography Synonym: ACN, Cyanomethane, Ethyl nitrile, Methyl cyanide CAS Number 75-05-8. Acetonitrile as a solvent used in liquid chromatography/mass spectrometry (LC/MS) of peptides and proteins is a relatively toxic solvent (LD 50 oral; rat; 2,460mg/kg) compared to alternatives like Try water/acetonitrile reverse phase chromatography. Ph Eur. The average DE for acetonitrile was determined to be 1.019. The recent worldwide shortage of acetonitrile has prompted interest in alternative solvents for liquid chromatography/mass spectrometry (LC/MS). Density (g/cm3): 0.79 . PRODUCT AVAILABILITY: Did you know you can view a product's availability right on the product page? ©Thomas Scientific 2021 All Rights Reserved. If selectivity or peak shape is poor, try LC grade methanol, but it can also be effective to set analytical conditions by carefully considering the properties of each solvent. Brand: Merck Description CAS number: 75-05-8 Chemical Formula: CH₃CN Molar Mass: 41.05 g/mol Synonyms: ACN, Methyl cyanide, Ethyl nitrile, Cyanomethane With their high degree of UV transmittance, low particle count, low acidity and alkalinity and low evaporation residue level, LiChrosolv® solvents are ideal for reproducible separations. (Take care, as column pressure may rise.) 1 , 5 Acetonitrile is most commonly used in the production of pharmaceuticals, especially in the synthesis of peptides. Generaly, the viscosity decreases with increase in concentration of the organic modifier, acetonitrile or methanol, respectively. During the synthetic route, solvents are used in many steps. Additives In Convergence Chromatography Acetonitrile as a solvent used in liquid chromatography/mass spectrometry (LC/MS) of peptides and proteins is relatively toxic compared to alternatives like methanol and acetone.
