Chemical Structure
Description
16b-Hydroxyestrone sodium-3-sulfate (CAS 54800-12-3), molecular formula C18H21O6SNa and molecular weight 388.41 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 16b-Hydroxyestrone sodium-3-sulfate (C18H21O6SNa) is characterized by a flavonoid core, a sulfone group, 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 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), 16b-Hydroxyestrone sodium-3-sulfate 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.
