Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies (R,E)-2-(4,8-Dimethylnona-3,7-dien-1-yl)-2,7-dimethyl-2H-chromen-5-ol (CAS 585534-03-8), a certified reference material (molecular formula C22H30O2, MW 326.47 g/mol) for analytical method development and quality control.
Owing to a steroid core, a hydroxyl group, an ether linkage, (R,E)-2-(4,8-Dimethylnona-3,7-dien-1-yl)-2,7-dimethyl-2H-chromen-5-ol is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 326.47 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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).
As a certified reference material (CRM), (R,E)-2-(4,8-Dimethylnona-3,7-dien-1-yl)-2,7-dimethyl-2H-chromen-5-ol 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.
