Chemical Structure
Description
The occurrence of 1143461-61-3 2-Bromo-5-(4-fluorophenyl)-1-pentene MFCD11915894 is closely related to fluorine/bromine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
1143461-61-3 2-Bromo-5-(4-fluorophenyl)-1-pentene MFCD11915894 (CAS 1143461-61-3) is a high-purity analytical reference standard with the molecular formula C11H12BrF and a molecular weight of 243.12 g/mol.
Owing to fluorine/bromine substitution, an aromatic ring system, 1143461-61-3 2-Bromo-5-(4-fluorophenyl)-1-pentene MFCD11915894 is typically off-white to pale yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 243.12 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
