Chemical Structure
Description
6-(bromomethyl)-5-oxaspiro[2.4]heptan-4-one (CAS 1803608-05-0) is a high-purity analytical reference standard with the molecular formula C7H9BrO2 and a molecular weight of 205.05 g/mol.
Based on its molecular formula C7H9BrO2, 6-(bromomethyl)-5-oxaspiro[2.4]heptan-4-one contains a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 205.05 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
