Chemical Structure
Description
The occurrence of 6-Bromobenzo[d][1,3]dioxole-4-carboxylic acid 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 6-Bromobenzo[d][1,3]dioxole-4-carboxylic acid (CAS 72744-57-1), a certified reference material (molecular formula C8H5BrO4, MW 245.03 g/mol) for analytical method development and quality control.
The molecular framework of 6-Bromobenzo[d][1,3]dioxole-4-carboxylic acid (C8H5BrO4) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
