Chemical Structure
Description
The occurrence of 2-[(5-Bromo-2-pyrimidinyl)oxy]ethanol is closely related to an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
2-[(5-Bromo-2-pyrimidinyl)oxy]ethanol (CAS 1246922-88-2) is a high-purity analytical reference standard with the molecular formula C6H7BrN2O2 and a molecular weight of 219.04 g/mol.
The molecular framework of 2-[(5-Bromo-2-pyrimidinyl)oxy]ethanol (C6H7BrN2O2) is characterized by an amide group, a carboxylic acid 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 presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
