Chemical Structure
Description
Owing to a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system, 2-Bromo-1-[4-(propan-2-yl)phenyl]propan-1-one is typically off-white to pale yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 255.15 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.
2-Bromo-1-[4-(propan-2-yl)phenyl]propan-1-one (CAS 820260-08-0) is a high-purity analytical reference standard with the molecular formula C12H15BrO and a molecular weight of 255.15 g/mol.
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.
