4-(Methylsulfonyl)benzonitrile 4-methanesulfonyl-benzonitrile 4-methylsulfonyl-benzonitrile 4-methylsulphonyl benzonitrile 4-methylsulfonylbenzonitrile 4-(methylsulphonyl)benzonitrile 4-methylsulfonyl benzonitrile 22821-76-7 CAS 22821-76-7

Description

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

4-(Methylsulfonyl)benzonitrile 4-methanesulfonyl-benzonitrile 4-methylsulfonyl-benzonitrile 4-methylsulphonyl benzonitrile 4-methylsulfonylbenzonitrile 4-(methylsulphonyl)benzonitrile 4-methylsulfonyl benzonitrile 22821-76-7 (CAS 22821-76-7), molecular formula C8H13NO2S and molecular weight 187.26 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, 4-(Methylsulfonyl)benzonitrile 4-methanesulfonyl-benzonitrile 4-methylsulfonyl-benzonitrile 4-methylsulphonyl benzonitrile 4-methylsulfonylbenzonitrile 4-(methylsulphonyl)benzonitrile 4-methylsulfonyl benzonitrile 22821-76-7 is typically white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 187.26 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
