Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 278.17 g/mol gives 2-Bromo-10H-phenothiazine distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
2-Bromo-10H-phenothiazine (CAS 66820-95-9) is a high-purity analytical reference standard with the molecular formula C12H8BrNS and a molecular weight of 278.17 g/mol.
Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, bromine substitution, 2-Bromo-10H-phenothiazine is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 278.17 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.
