Chemical Structure

1-(3-Bromophenyl)-3-methyl-1-butanone CAS 857803-65-7 chemical structure

Description

The occurrence of 1-(3-Bromophenyl)-3-methyl-1-butanone is closely related to a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

1-(3-Bromophenyl)-3-methyl-1-butanone (CAS 857803-65-7), molecular formula C11H13BrO and molecular weight 241.12 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system, 1-(3-Bromophenyl)-3-methyl-1-butanone is typically off-white to pale yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 241.12 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.

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.
