Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including n-[(2-chlorophenyl)methyl]-2-fluorobenzene-1-sulfonamide.
CATO supplies n-[(2-chlorophenyl)methyl]-2-fluorobenzene-1-sulfonamide (CAS 722478-55-9), a certified reference material (molecular formula C13H11ClFNO2S, MW 299.75 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, fluorine/chlorine substitution, n-[(2-chlorophenyl)methyl]-2-fluorobenzene-1-sulfonamide is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 299.75 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), n-[(2-chlorophenyl)methyl]-2-fluorobenzene-1-sulfonamide 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.
