Chemical Structure
Description
The occurrence of 1,5-Bis(2-bromo-5-hydroxyphenyl)pentan-3-one is closely related to a steroid core, a hydroxyl group, an ether linkage, bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
1,5-Bis(2-bromo-5-hydroxyphenyl)pentan-3-one (CAS 1427054-10-1), molecular formula C17H16Br2O3 and molecular weight 428.12 g/mol, is a CATO reference standard with documented purity and traceability.
1,5-Bis(2-bromo-5-hydroxyphenyl)pentan-3-one (C17H16Br2O3) contains a steroid core, a hydroxyl group, an ether linkage, bromine substitution. 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.
