Description

Compared with other compounds in its class, the molecular weight of 419.11 g/mol gives 2,4-Dibromo-9-methoxy-10,11-dihydro-5-azatetraphene distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

2,4-Dibromo-9-methoxy-10,11-dihydro-5-azatetraphene (CAS 865658-91-9), molecular formula C18H13Br2NO and molecular weight 419.11 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, bromine substitution, 2,4-Dibromo-9-methoxy-10,11-dihydro-5-azatetraphene is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 419.11 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.
