Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 520.38 g/mol gives 2,5-Bis(bromomethyl)-1,4-bis(octyloxy)benzene distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 2,5-Bis(bromomethyl)-1,4-bis(octyloxy)benzene (CAS 147274-72-4), a certified reference material (molecular formula C24H40Br2O2, MW 520.38 g/mol) for analytical method development and quality control.
2,5-Bis(bromomethyl)-1,4-bis(octyloxy)benzene (C24H40Br2O2) 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
