4-[Bis(4-methoxyphenyl)amino]benzaldehyde CAS 89115-20-8 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 4-[Bis(4-methoxyphenyl)amino]benzaldehyde.

CATO supplies 4-[Bis(4-methoxyphenyl)amino]benzaldehyde (CAS 89115-20-8), a certified reference material (molecular formula C21H19NO3, MW 333.38 g/mol) for analytical method development and quality control.

Structurally, 4-[Bis(4-methoxyphenyl)amino]benzaldehyde (C21H19NO3) contains a steroid core, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 13.0, corresponding to approximately 13 ring(s) or double-bond equivalent(s). With a molecular weight of 333.38 g/mol, it falls into the moderately-high-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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-[Bis(4-methoxyphenyl)amino]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.
