2-Bromo-1-(4-fluoro-3-methylphenyl)ethan-1-one CAS 63529-31-7

Description

Compared with other compounds in its class, the molecular weight of 231.06 g/mol gives 2-Bromo-1-(4-fluoro-3-methylphenyl)ethan-1-one distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

2-Bromo-1-(4-fluoro-3-methylphenyl)ethan-1-one (CAS 63529-31-7), molecular formula C9H8BrFO and molecular weight 231.06 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a hydroxyl group, an ether linkage, fluorine/bromine substitution, an aromatic ring system, 2-Bromo-1-(4-fluoro-3-methylphenyl)ethan-1-one is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 231.06 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
