CATO supplies 2-(METHYLSULFONYL)ACETONITRILE 2-Methanesulfonylacetonitrile 2274-42-2 AS06226 CYANOMETHYL METHYL SULPHONE METHANESULPHONYLACETONITRILE METHYLSULFONYLACETONITRILE (CAS 2274-42-2), a certified reference material (molecular formula C3H5NO2S, MW 119.14 g/mol) for analytical method development and quality control.
2-(METHYLSULFONYL)ACETONITRILE 2-Methanesulfonylacetonitrile 2274-42-2 AS06226 CYANOMETHYL METHYL SULPHONE METHANESULPHONYLACETONITRILE METHYLSULFONYLACETONITRILE (C3H5NO2S) contains an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage. The carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
