1-(3-Bromo-4-fluorophenyl)-4-cyclopropylbutane-1,3-dione CAS 2065223-86-9

Description

1-(3-Bromo-4-fluorophenyl)-4-cyclopropylbutane-1,3-dione (CAS 2065223-86-9), molecular formula C13H12BrFO2 and molecular weight 299.14 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C13H12BrFO2, 1-(3-Bromo-4-fluorophenyl)-4-cyclopropylbutane-1,3-dione contains a carboxylic acid group, 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 299.14 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.

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

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.
