Chemical Structure
Description
The molecular framework of 1-(2-Methoxyphenyl)-4-((3-methyl-4-propoxyphenyl)sulfonyl)piperazine (C21H28N2O4S) is characterized by a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage. 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).
1-(2-Methoxyphenyl)-4-((3-methyl-4-propoxyphenyl)sulfonyl)piperazine (CAS 898650-55-0), molecular formula C21H28N2O4S and molecular weight 404.52 g/mol, is a CATO reference standard with documented purity and traceability.
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.
