Description

Compared with other compounds in its class, the molecular weight of 227.10 g/mol gives 5-Bromo-4,6-dimethyl-2,3-dihydrobenzofuran distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

5-Bromo-4,6-dimethyl-2,3-dihydrobenzofuran (CAS 820258-91-1), molecular formula C10H11BrO and molecular weight 227.10 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 5-Bromo-4,6-dimethyl-2,3-dihydrobenzofuran (C10H11BrO) contains a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 5.0, corresponding to approximately 5 ring(s) or double-bond equivalent(s). With a molecular weight of 227.10 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).

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

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.
