Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 5-PREGNEN-6, 16α-DIMETHYL-3β-OL-20-ONE.
5-PREGNEN-6, 16α-DIMETHYL-3β-OL-20-ONE (CAS 5888-08-4) is a high-purity analytical reference standard with the molecular formula C23H36O2 and a molecular weight of 344.53 g/mol.
Owing to a steroid core, a hydroxyl group, an ether linkage, 5-PREGNEN-6, 16α-DIMETHYL-3β-OL-20-ONE is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 344.53 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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), 5-PREGNEN-6, 16α-DIMETHYL-3β-OL-20-ONE 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.
