Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 235.64 g/mol gives 1-Chloro-4-((nitromethyl)sulfonyl)benzene distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 1-Chloro-4-((nitromethyl)sulfonyl)benzene (CAS 66073-97-0), a certified reference material (molecular formula C7H6ClNO4S, MW 235.64 g/mol) for analytical method development and quality control.
Owing to an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system, 1-Chloro-4-((nitromethyl)sulfonyl)benzene is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 235.64 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), 1-Chloro-4-((nitromethyl)sulfonyl)benzene 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.
