Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 330.42 g/mol gives 122717-54-8 Kaura-1,16-diene-3,15-dione,7,14-dihydroxy-, (7a,14R)- distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
122717-54-8 Kaura-1,16-diene-3,15-dione,7,14-dihydroxy-, (7a,14R)- (CAS 122717-54-8) is a high-purity analytical reference standard with the molecular formula C20H26O4 and a molecular weight of 330.42 g/mol.
Owing to a flavonoid core, a hydroxyl group, an ether linkage, 122717-54-8 Kaura-1,16-diene-3,15-dione,7,14-dihydroxy-, (7a,14R)- is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 330.42 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).
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), 122717-54-8 Kaura-1,16-diene-3,15-dione,7,14-dihydroxy-, (7a,14R)- 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.
