(S)-2-(Bromomethyl)-2,3-dihydrobenzo[b][1,4]dioxine (CAS 1618132-41-4) is a high-purity analytical reference standard with the molecular formula C9H9BrO2 and a molecular weight of 229.07 g/mol.
The molecular framework of (S)-2-(Bromomethyl)-2,3-dihydrobenzo[b][1,4]dioxine (C9H9BrO2) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
