Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 272.37 g/mol gives Z,Z-Dienestrol-d6 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Z,Z-Dienestrol-d6 (CAS 91297-99-3) is a high-purity analytical reference standard with the molecular formula C18H12D6O2 and a molecular weight of 272.37 g/mol.
The molecular framework of Z,Z-Dienestrol-d6 (C18H12D6O2) is characterized by deuterium isotope labeling, a steroid 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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
As a certified reference material (CRM), Z,Z-Dienestrol-d6 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.
