Chemical Structure
Description
As a certified reference material (CRM), 1-Nitro-4-[(trifluoromethyl)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.
CATO supplies 1-Nitro-4-[(trifluoromethyl)sulfonyl]benzene (CAS 432-87-1), a certified reference material (molecular formula C7H4F3NO4S, MW 255.17 g/mol) for analytical method development and quality control.
1-Nitro-4-[(trifluoromethyl)sulfonyl]benzene (C7H4F3NO4S) contains an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
