Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 291.18 g/mol gives 1-(Benzyloxy)-2-bromo-4,5-dimethylbenzene distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
1-(Benzyloxy)-2-bromo-4,5-dimethylbenzene (CAS 1809168-72-6), molecular formula C15H15BrO and molecular weight 291.18 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a hydroxyl group, an ether linkage, bromine substitution, a polycyclic aromatic system, 1-(Benzyloxy)-2-bromo-4,5-dimethylbenzene is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 291.18 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.
