Chemical Structure

4,5-Dihydro-6-ketonorethindrone CAS 53697-08-8 chemical structure

Description

The molecular framework of 4,5-Dihydro-6-ketonorethindrone (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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

CATO supplies 4,5-Dihydro-6-ketonorethindrone (CAS 53697-08-8), a certified reference material (molecular formula C20H26O3, MW 314.42 g/mol) for analytical method development and quality control.

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.
