17,20:20,21-Bis(methylenedioxy)pregna-1,4-diene-3,11-dione(Mixture of Diastereomers) CAS 26341-55-9 chemical structure

Description

As a certified reference material (CRM), 17,20:20,21-Bis(methylenedioxy)pregna-1,4-diene-3,11-dione(Mixture of Diastereomers) 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.

17,20:20,21-Bis(methylenedioxy)pregna-1,4-diene-3,11-dione(Mixture of Diastereomers) (CAS 26341-55-9) is a high-purity analytical reference standard with the molecular formula C23H28O6 and a molecular weight of 400.46 g/mol.

Structurally, 17,20:20,21-Bis(methylenedioxy)pregna-1,4-diene-3,11-dione(Mixture of Diastereomers) (C23H28O6) contains a flavonoid core, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 10.0, corresponding to approximately 10 ring(s) or double-bond equivalent(s). With a molecular weight of 400.46 g/mol, it falls into the moderately-high-molecular-weight range. 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).

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.
