4-(4-Bromophenyl)-5-[(Z)-2-(3-methylphenyl)diazen-1-yl]-2-(pyridin-3-yl)pyrimidine CAS 339279-69-5

Description

4-(4-Bromophenyl)-5-[(Z)-2-(3-methylphenyl)diazen-1-yl]-2-(pyridin-3-yl)pyrimidine (CAS 339279-69-5) is a high-purity analytical reference standard with the molecular formula C22H16BrN5 and a molecular weight of 430.30 g/mol.

The molecular framework of 4-(4-Bromophenyl)-5-[(Z)-2-(3-methylphenyl)diazen-1-yl]-2-(pyridin-3-yl)pyrimidine (C22H16BrN5) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, bromine substitution. 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.
