4,4'-(Mesitylazanediyl)dibenzaldehyde CAS 149676-08-4

Description

The occurrence of 4,4'-(Mesitylazanediyl)dibenzaldehyde is closely related to a steroid core, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

4,4'-(Mesitylazanediyl)dibenzaldehyde (CAS 149676-08-4), molecular formula C23H21NO2 and molecular weight 343.42 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 4,4'-(Mesitylazanediyl)dibenzaldehyde (C23H21NO2) 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 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.
