Description
CATO supplies Methyl 7-bromo-8-(1-methoxycyclohexyl)-2-oxo-2H-selenopheno[3,2-h]chromene-3-carboxylate (CAS 2173398-10-0), a certified reference material (molecular formula C20H19BrO5Se, MW 498.23 g/mol) for analytical method development and quality control.
Methyl 7-bromo-8-(1-methoxycyclohexyl)-2-oxo-2H-selenopheno[3,2-h]chromene-3-carboxylate (C20H19BrO5Se) contains a flavonoid core, a hydroxyl group, an ether linkage, bromine substitution. Halogen substitution raises its density and boiling point, 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.
As a certified reference material (CRM), Methyl 7-bromo-8-(1-methoxycyclohexyl)-2-oxo-2H-selenopheno[3,2-h]chromene-3-carboxylate meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
