Description

The occurrence of 1-(1-Benzofuran-2-yl)-2-bromoethan-1-one 1-(1-benzofuran-2-yl)-2-bromoethanone 1-benzofuran-2-yl-2-bromo-ethanone 2-(2-bromoacetyl)benzo[b]furan 2-(2-bromoacetyl)benzofuran 23489-36-3 is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

1-(1-Benzofuran-2-yl)-2-bromoethan-1-one 1-(1-benzofuran-2-yl)-2-bromoethanone 1-benzofuran-2-yl-2-bromo-ethanone 2-(2-bromoacetyl)benzo[b]furan 2-(2-bromoacetyl)benzofuran 23489-36-3 (CAS 23489-36-3) is a high-purity analytical reference standard with the molecular formula C10H15BrO2 and a molecular weight of 247.13 g/mol.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution, 1-(1-Benzofuran-2-yl)-2-bromoethan-1-one 1-(1-benzofuran-2-yl)-2-bromoethanone 1-benzofuran-2-yl-2-bromo-ethanone 2-(2-bromoacetyl)benzo[b]furan 2-(2-bromoacetyl)benzofuran 23489-36-3 is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 247.13 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.

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.
