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.
2-Chloro-n-[(4-methoxyphenyl)methyl]-n-[1-(thiophen-2-yl)propan-2-yl]acetamide (CAS 879319-07-0), molecular formula C17H20ClNO2S and molecular weight 337.86 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 2-Chloro-n-[(4-methoxyphenyl)methyl]-n-[1-(thiophen-2-yl)propan-2-yl]acetamide (C17H20ClNO2S) is characterized by a steroid 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 its high hydrophobicity (logP), 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.
As a certified reference material (CRM), 2-Chloro-n-[(4-methoxyphenyl)methyl]-n-[1-(thiophen-2-yl)propan-2-yl]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.
