2-Bromo-1-(3-methylquinoxalin-2-yl)ethan-1-one CAS 5498-44-2

Description

The occurrence of 2-Bromo-1-(3-methylquinoxalin-2-yl)ethan-1-one is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

2-Bromo-1-(3-methylquinoxalin-2-yl)ethan-1-one (CAS 5498-44-2) is a high-purity analytical reference standard with the molecular formula C11H9BrN2O and a molecular weight of 265.11 g/mol.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, bromine substitution, 2-Bromo-1-(3-methylquinoxalin-2-yl)ethan-1-one is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 265.11 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.
