Chemical Structure
Description
The occurrence of 7-Bromobenzo[d][1,3]dioxol-5-ol is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 7-Bromobenzo[d][1,3]dioxol-5-ol (CAS 66799-94-8), a certified reference material (molecular formula C7H5BrO3, MW 217.02 g/mol) for analytical method development and quality control.
Based on its molecular formula C7H5BrO3, 7-Bromobenzo[d][1,3]dioxol-5-ol contains a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 217.02 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).
