4-((4-(Dioctylamino)phenyl)diazenyl)-3-nitrobenzaldehyde CAS 497151-94-7

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 4-((4-(Dioctylamino)phenyl)diazenyl)-3-nitrobenzaldehyde.

4-((4-(Dioctylamino)phenyl)diazenyl)-3-nitrobenzaldehyde (CAS 497151-94-7) is a high-purity analytical reference standard with the molecular formula C29H42N4O3 and a molecular weight of 494.67 g/mol.

The molecular framework of 4-((4-(Dioctylamino)phenyl)diazenyl)-3-nitrobenzaldehyde (C29H42N4O3) 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 the protonation state of its nitrogen-containing groups, 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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
