Chemical Structure
Description
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.
N-{4-[(2-chlorophenyl)sulfanyl]phenyl}-3-methylbenzamide (CAS 251096-72-7), molecular formula C20H16ClNOS and molecular weight 353.87 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of N-{4-[(2-chlorophenyl)sulfanyl]phenyl}-3-methylbenzamide (C20H16ClNOS) is characterized by a steroid core, an amide group, sulfur-containing functionality, 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).
CATO manufactures N-{4-[(2-chlorophenyl)sulfanyl]phenyl}-3-methylbenzamide 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.
