Description
As a certified reference material (CRM), 2-[N-(4-Chlorophenyl)4-chlorobenzenesulfonamido]acetic acid 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.
2-[N-(4-Chlorophenyl)4-chlorobenzenesulfonamido]acetic acid (CAS 478260-83-2), molecular formula C14H11Cl2NO4S and molecular weight 360.21 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 2-[N-(4-Chlorophenyl)4-chlorobenzenesulfonamido]acetic acid (C14H11Cl2NO4S) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
