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 n-(2-Chloro-5-(methylsulfonyl)phenyl)-2-methoxyacetamide.
CATO supplies n-(2-Chloro-5-(methylsulfonyl)phenyl)-2-methoxyacetamide (CAS 1223534-37-9), a certified reference material (molecular formula C10H12ClNO4S, MW 277.72 g/mol) for analytical method development and quality control.
The molecular framework of n-(2-Chloro-5-(methylsulfonyl)phenyl)-2-methoxyacetamide (C10H12ClNO4S) 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.
As a certified reference material (CRM), n-(2-Chloro-5-(methylsulfonyl)phenyl)-2-methoxyacetamide 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.
