4-Bromo-1-(4-fluorophenyl)butan-1-one CAS 40132-01-2

Description

Compared with other compounds in its class, the molecular weight of 245.09 g/mol gives 4-Bromo-1-(4-fluorophenyl)butan-1-one distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

4-Bromo-1-(4-fluorophenyl)butan-1-one (CAS 40132-01-2), molecular formula C10H10BrFO and molecular weight 245.09 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C10H10BrFO, 4-Bromo-1-(4-fluorophenyl)butan-1-one contains a hydroxyl group, an ether linkage, fluorine/bromine substitution, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 245.09 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.

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.
