Chemical Structure
Description
Based on its molecular formula C15H15BrO, 1-Bromo-2-ethyl-4-[(phenylmethyl)oxy]benzene contains a hydroxyl group, an ether linkage, bromine substitution, a polycyclic aromatic system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 291.18 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
1-Bromo-2-ethyl-4-[(phenylmethyl)oxy]benzene (CAS 668477-51-8) is a high-purity analytical reference standard with the molecular formula C15H15BrO and a molecular weight of 291.18 g/mol.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
