Description
CATO supplies 30220-43-0 Kaur-16-en-15-one,7,20-epoxy-1,6,7-trihydroxy-, (1a,6b,7a)- (CAS 30220-43-0), a certified reference material (molecular formula C20H28O5, MW 348.43 g/mol) for analytical method development and quality control.
The molecular framework of 30220-43-0 Kaur-16-en-15-one,7,20-epoxy-1,6,7-trihydroxy-, (1a,6b,7a)- (C20H28O5) is characterized by a flavonoid core, a hydroxyl group, an ether linkage. 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.
As a certified reference material (CRM), 30220-43-0 Kaur-16-en-15-one,7,20-epoxy-1,6,7-trihydroxy-, (1a,6b,7a)- 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.
