Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 4-(2-Chloroethyl)-N-(2-methoxyethyl)benzenesulfonamide.
4-(2-Chloroethyl)-N-(2-methoxyethyl)benzenesulfonamide (CAS 1018334-05-8), molecular formula C11H16ClNO3S and molecular weight 277.77 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 4-(2-Chloroethyl)-N-(2-methoxyethyl)benzenesulfonamide (C11H16ClNO3S) 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 its high hydrophobicity (logP), 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.
As a certified reference material (CRM), 4-(2-Chloroethyl)-N-(2-methoxyethyl)benzenesulfonamide 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.
