Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 289.58 g/mol gives 6-Bromo-4-chloro-2-(methylsulfanyl)quinazoline distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
6-Bromo-4-chloro-2-(methylsulfanyl)quinazoline (CAS 1003043-76-2) is a high-purity analytical reference standard with the molecular formula C9H6BrClN2S and a molecular weight of 289.58 g/mol.
Structurally, 6-Bromo-4-chloro-2-(methylsulfanyl)quinazoline (C9H6BrClN2S) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, chlorine/bromine substitution. The molecule exhibits a degree of unsaturation (DBE) of 7.0, corresponding to approximately 7 ring(s) or double-bond equivalent(s). With a molecular weight of 289.58 g/mol, it falls into the medium-molecular-weight range. 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.
