Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 215.66 g/mol gives 2-Chloro-4-(methylsulfonyl)benzonitrile distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 2-Chloro-4-(methylsulfonyl)benzonitrile (CAS 869586-86-7), a certified reference material (molecular formula C8H6ClNO2S, MW 215.66 g/mol) for analytical method development and quality control.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution, 2-Chloro-4-(methylsulfonyl)benzonitrile is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 215.66 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 2-Chloro-4-(methylsulfonyl)benzonitrile meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
