4-(5-bromo-1H-1,3-benzodiazol-2-yl)aniline (CAS 519042-70-7) is a high-purity analytical reference standard with the molecular formula C13H10BrN3 and a molecular weight of 288.14 g/mol.
The molecular framework of 4-(5-bromo-1H-1,3-benzodiazol-2-yl)aniline (C13H10BrN3) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, bromine substitution. 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.
