17-beta-Hydroxy Exemestane Epoxide (Mixture of Diastereomers) CAS 1331732-05-8

Description

Compared with other compounds in its class, the molecular weight of 314.42 g/mol gives 17-beta-Hydroxy Exemestane Epoxide (Mixture of Diastereomers) distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies 17-beta-Hydroxy Exemestane Epoxide (Mixture of Diastereomers) (CAS 1331732-05-8), a certified reference material (molecular formula C20H26O3, MW 314.42 g/mol) for analytical method development and quality control.

The molecular framework of 17-beta-Hydroxy Exemestane Epoxide (Mixture of Diastereomers) (C20H26O3) is characterized by 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 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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
