Chemical Structure
Description
The occurrence of 17,17-Ethylenedioxy-1,3,5(10)-estratriene-3,16α-diol-d is closely related to deuterium isotope labeling, a flavonoid core, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
17,17-Ethylenedioxy-1,3,5(10)-estratriene-3,16α-diol-d (CAS 1259370-24-5), molecular formula C20H21D5O4 and molecular weight 335.45 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 17,17-Ethylenedioxy-1,3,5(10)-estratriene-3,16α-diol-d (C20H21D5O4) is characterized by deuterium isotope labeling, a flavonoid core, a hydroxyl group, an ether linkage. 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.
CATO manufactures 17,17-Ethylenedioxy-1,3,5(10)-estratriene-3,16α-diol-d under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
