Chemical Structure
Description
As a certified reference material (CRM), Venlafaxine Impurity 38 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.
Venlafaxine Impurity 38 (CAS 93413-44-6) is a certified pharmaceutical impurity reference standard with the molecular formula C17H27NO2 and a molecular weight of 277.40 g/mol.
The molecular framework of Venlafaxine Impurity 38 (C17H27NO2) 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 supports related-substances testing and method development in line with ICH Q3A/Q3B guidance on impurity control, and is suitable for system suitability testing and forced-degradation studies.
