Description
As a certified reference material (CRM), 39388-57-3 Kaur-16-en-15-one,1,7,14-trihydroxy-, (1a,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.
39388-57-3 Kaur-16-en-15-one,1,7,14-trihydroxy-, (1a,7a,14R)- (CAS 39388-57-3), molecular formula C20H30O4 and molecular weight 334.45 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a steroid core, a hydroxyl group, an ether linkage, 39388-57-3 Kaur-16-en-15-one,1,7,14-trihydroxy-, (1a,7a,14R)- is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 334.45 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
