Chemical Structure
Description
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.
4-bromo-2-(bromomethyl)-1-(pentyloxy)benzene (CAS 1094273-06-9), molecular formula C12H16Br2O and molecular weight 336.06 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 4-bromo-2-(bromomethyl)-1-(pentyloxy)benzene (C12H16Br2O) is characterized by a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system. 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 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.
