(20β)-17,19-Epoxy-19,20-dihydro-10,17-dihydroxy-4,21-dimethyl-18-Norsarpaganium CAS 98243-58-4

Description

The occurrence of (20β)-17,19-Epoxy-19,20-dihydro-10,17-dihydroxy-4,21-dimethyl-18-Norsarpaganium is closely related to a steroid core, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

(20β)-17,19-Epoxy-19,20-dihydro-10,17-dihydroxy-4,21-dimethyl-18-Norsarpaganium (CAS 98243-58-4) is a high-purity analytical reference standard with the molecular formula C20H25N2O3 and a molecular weight of 341.42 g/mol.

The molecular framework of (20β)-17,19-Epoxy-19,20-dihydro-10,17-dihydroxy-4,21-dimethyl-18-Norsarpaganium (C20H25N2O3) is characterized by a steroid core, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing 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).

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.
