4-bromo-2-(2H-1,2,3,4-tetrazol-5-yl)phenol (CAS 874815-05-1) is a high-purity analytical reference standard with the molecular formula C7H5BrN4O and a molecular weight of 241.04 g/mol.
The molecular framework of 4-bromo-2-(2H-1,2,3,4-tetrazol-5-yl)phenol (C7H5BrN4O) is characterized by an amide group, a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system. 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. 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.
