Chemical Structure
Description
4-[4-(dimethylamino)phenyl]benzaldehyde (CAS 173991-06-5) is a high-purity analytical reference standard with the molecular formula C15H15NO and a molecular weight of 225.29 g/mol.
The molecular framework of 4-[4-(dimethylamino)phenyl]benzaldehyde (C15H15NO) is characterized by a nitrogen-containing heterocyclic scaffold, 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
As a certified reference material (CRM), 4-[4-(dimethylamino)phenyl]benzaldehyde 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.
