Chemical Structure

7-bromo-4-fluoro-indan-1-one CAS 881189-73-7 chemical structure

Description

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.

7-bromo-4-fluoro-indan-1-one (CAS 881189-73-7) is a high-purity analytical reference standard with the molecular formula C9H12BrFO and a molecular weight of 235.09 g/mol.

Structurally, 7-bromo-4-fluoro-indan-1-one (C9H12BrFO) contains a hydroxyl group, an ether linkage, fluorine/bromine substitution. The molecule exhibits a degree of unsaturation (DBE) of 3.0, corresponding to approximately 3 ring(s) or double-bond equivalent(s). With a molecular weight of 235.09 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.
