5-Bromo-2-methyl-2,3-dihydrobenzofuran CAS 102292-30-8

Description

The occurrence of 5-Bromo-2-methyl-2,3-dihydrobenzofuran is closely related to a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

5-Bromo-2-methyl-2,3-dihydrobenzofuran (CAS 102292-30-8), molecular formula C9H9BrO and molecular weight 213.07 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C9H9BrO, 5-Bromo-2-methyl-2,3-dihydrobenzofuran contains a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 213.07 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.
