Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 257.08 g/mol gives Alpha-bromo-3'-acetoxyacetophenone distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies Alpha-bromo-3'-acetoxyacetophenone (CAS 38396-89-3), a certified reference material (molecular formula C10H9BrO3, MW 257.08 g/mol) for analytical method development and quality control.
Alpha-bromo-3'-acetoxyacetophenone (C10H9BrO3) contains a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system. It is notably hygroscopic, halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
