Chemical Structure
Description
The molecular framework of 1,5-Dibromo-2,3-dihydro-1H-indene (C9H8Br2) is characterized by 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.
1,5-Dibromo-2,3-dihydro-1H-indene (CAS 355016-52-3) is a high-purity analytical reference standard with the molecular formula C9H8Br2 and a molecular weight of 275.97 g/mol.
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.
