Chemical Structure
Description
6-Bromobenzo[d][1,3]dioxole-4-carbaldehyde (CAS 72744-55-9) is a high-purity analytical reference standard with the molecular formula C8H5BrO3 and a molecular weight of 229.03 g/mol.
Structurally, 6-Bromobenzo[d][1,3]dioxole-4-carbaldehyde (C8H5BrO3) contains a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 6.0, corresponding to approximately 6 ring(s) or double-bond equivalent(s). With a molecular weight of 229.03 g/mol, it falls into the medium-molecular-weight range. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
