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-(2-((4-chlorophenyl)thio)ethyl)-2-(m-tolyl)acetamide (CAS 338399-86-3), molecular formula C17H18ClNOS and molecular weight 319.85 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of N-(2-((4-chlorophenyl)thio)ethyl)-2-(m-tolyl)acetamide (C17H18ClNOS) 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).
As a certified reference material (CRM), N-(2-((4-chlorophenyl)thio)ethyl)-2-(m-tolyl)acetamide 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.
