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.
1-([1,1'-Biphenyl]-2-yl)-2-bromoethanone (CAS 61236-14-4) is a high-purity analytical reference standard with the molecular formula C14H11BrO and a molecular weight of 275.14 g/mol.
Owing to a hydroxyl group, an ether linkage, bromine substitution, a polycyclic aromatic system, 1-([1,1'-Biphenyl]-2-yl)-2-bromoethanone is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 275.14 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
