2-((N-benzyl-4-methylphenyl)sulfonamido)-N-(5-chloro-2-methoxyphenyl)acetamide CAS 332163-70-9 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 2-((N-benzyl-4-methylphenyl)sulfonamido)-N-(5-chloro-2-methoxyphenyl)acetamide.

2-((N-benzyl-4-methylphenyl)sulfonamido)-N-(5-chloro-2-methoxyphenyl)acetamide (CAS 332163-70-9), molecular formula C23H23ClN2O4S and molecular weight 458.96 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 2-((N-benzyl-4-methylphenyl)sulfonamido)-N-(5-chloro-2-methoxyphenyl)acetamide (C23H23ClN2O4S) is characterized by a flavonoid core, 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

CATO manufactures 2-((N-benzyl-4-methylphenyl)sulfonamido)-N-(5-chloro-2-methoxyphenyl)acetamide under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
