Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 217.06 g/mol gives 1-Bromo-2,3-dimethoxybenzene distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
1-Bromo-2,3-dimethoxybenzene (CAS 5424-43-1), molecular formula C8H9BrO2 and molecular weight 217.06 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 1-Bromo-2,3-dimethoxybenzene (C8H9BrO2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 4.0, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 217.06 g/mol, it falls into the medium-molecular-weight range. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
