Chemical Structure
Description
The occurrence of 1-Bromo-4-methoxybicyclo[2.2.2]octan-2-one is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
1-Bromo-4-methoxybicyclo[2.2.2]octan-2-one (CAS 88888-28-2) is a high-purity analytical reference standard with the molecular formula C9H13BrO2 and a molecular weight of 233.10 g/mol.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution, 1-Bromo-4-methoxybicyclo[2.2.2]octan-2-one is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 233.10 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
