CATO supplies 59859-58-4 8Y719ZLX8C Femoxetine Femoxetine [INN] (+)-trans-3-((p-Methoxyphenoxy)methyl)-1-methyl-4-phenylpiperidine Piperidine, 3-((4-methoxyphenoxy)methyl)-1-methyl-4-phenyl-, (3R-trans)- Femoxetina [INN-Spanish] Femoxetinum [INN-Latin] Femoxetina Femoxetinum UNII-8Y719ZLX8C (+)-Femoxetine (CAS 59859-58-4), a certified reference material (molecular formula C20H25NO2, MW 311.42 g/mol) for analytical method development and quality control.

The molecular framework of 59859-58-4 8Y719ZLX8C Femoxetine Femoxetine [INN] (+)-trans-3-((p-Methoxyphenoxy)methyl)-1-methyl-4-phenylpiperidine Piperidine, 3-((4-methoxyphenoxy)methyl)-1-methyl-4-phenyl-, (3R-trans)- Femoxetina [INN-Spanish] Femoxetinum [INN-Latin] Femoxetina Femoxetinum UNII-8Y719ZLX8C (+)-Femoxetine (C20H25NO2) is characterized by a steroid core, an amide group, a hydroxyl group, an ether linkage. 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.
