Chemical Structure
Description
The molecular framework of 7-bromo-1-benzothiophene-2-carbaldehyde (C9H13BrOS) is characterized by sulfur-containing functionality, a hydroxyl group, an ether linkage, bromine substitution. 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.
7-bromo-1-benzothiophene-2-carbaldehyde (CAS 19075-47-9) is a high-purity analytical reference standard with the molecular formula C9H13BrOS and a molecular weight of 249.17 g/mol.
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.
