Chemical Structure
Description
CATO supplies 1-Bromo-4-(4-prop-2-enoxyphenyl)benzene (CAS 918823-91-3), a certified reference material (molecular formula C15H13BrO, MW 289.17 g/mol) for analytical method development and quality control.
Structurally, 1-Bromo-4-(4-prop-2-enoxyphenyl)benzene (C15H13BrO) contains a hydroxyl group, an ether linkage, bromine substitution, a polycyclic aromatic system. The molecule exhibits a degree of unsaturation (DBE) of 9.0, corresponding to approximately 9 ring(s) or double-bond equivalent(s). With a molecular weight of 289.17 g/mol, it falls into the medium-molecular-weight range. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
