Description
As a certified reference material (CRM), Estradiol 3,17-Dienanthate 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.
Estradiol 3,17-Dienanthate (CAS 7732-97-0) is a high-purity analytical reference standard with the molecular formula C32H48O4 and a molecular weight of 496.72 g/mol.
The molecular framework of Estradiol 3,17-Dienanthate (C32H48O4) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), 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.
