Description
As a certified reference material (CRM), 21β-HydroxyeplerenoneDISCONTINUED. Offer H804508 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.
CATO supplies 21β-HydroxyeplerenoneDISCONTINUED. Offer H804508 (CAS 1633889-97-0), a certified reference material (molecular formula C24H30O7, MW 430.49 g/mol) for analytical method development and quality control.
21β-HydroxyeplerenoneDISCONTINUED. Offer H804508 (C24H30O7) contains a flavonoid core, a hydroxyl group, an ether linkage. The carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
