Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
6-Bromo-7-hydroxy-2,2-dimethyl-4H-benzo[d][1,3]dioxin-4-one (CAS 531501-41-4) is a high-purity analytical reference standard with the molecular formula C10H9BrO4 and a molecular weight of 273.08 g/mol.
Structurally, 6-Bromo-7-hydroxy-2,2-dimethyl-4H-benzo[d][1,3]dioxin-4-one (C10H9BrO4) 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 6.0, corresponding to approximately 6 ring(s) or double-bond equivalent(s). With a molecular weight of 273.08 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).
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.
