Chemical Structure

6-Bromo-1,4-dioxaspiro[4.4]non-6-ene CAS 68241-78-1 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 205.05 g/mol gives 6-Bromo-1,4-dioxaspiro[4.4]non-6-ene distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

6-Bromo-1,4-dioxaspiro[4.4]non-6-ene (CAS 68241-78-1) is a high-purity analytical reference standard with the molecular formula C7H9BrO2 and a molecular weight of 205.05 g/mol.

Structurally, 6-Bromo-1,4-dioxaspiro[4.4]non-6-ene (C7H9BrO2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, 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 205.05 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.
