Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 470.17 g/mol gives 7-Bromo-8-(1-hydroxycyclohexyl)-2-oxo-2H-selenopheno[3,2-h]chromene-3-carboxylic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 7-Bromo-8-(1-hydroxycyclohexyl)-2-oxo-2H-selenopheno[3,2-h]chromene-3-carboxylic acid (CAS 2173398-17-7), a certified reference material (molecular formula C18H15BrO5Se, MW 470.17 g/mol) for analytical method development and quality control.
The molecular framework of 7-Bromo-8-(1-hydroxycyclohexyl)-2-oxo-2H-selenopheno[3,2-h]chromene-3-carboxylic acid (C18H15BrO5Se) is characterized by a flavonoid core, 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. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
