Chemical Structure
Description
As a certified reference material (CRM), Paroxetine 4-Hydroxy Metabolite 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.
Paroxetine 4-Hydroxy Metabolite (CAS 112058-90-9) is a high-purity analytical reference standard with the molecular formula C19H22FNO3 and a molecular weight of 331.38 g/mol.
The molecular framework of Paroxetine 4-Hydroxy Metabolite (C19H22FNO3) is characterized by a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine 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.
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.
