Chemical Structure
Description
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.
3,5-Dibromo-2-((2-chlorobenzyl)oxy)benzaldehyde (CAS 792945-79-0) is a high-purity analytical reference standard with the molecular formula C14H9Br2ClO2 and a molecular weight of 404.48 g/mol.
Based on its molecular formula C14H9Br2ClO2, 3,5-Dibromo-2-((2-chlorobenzyl)oxy)benzaldehyde contains a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine/bromine substitution, a polycyclic aromatic system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 404.48 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
