5β-Androst-1-ene-3,17-dione CAS 571-39-1

Description

Compared with other compounds in its class, the molecular weight of 286.41 g/mol gives 5β-Androst-1-ene-3,17-dione distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

5β-Androst-1-ene-3,17-dione (CAS 571-39-1), molecular formula C19H26O2 and molecular weight 286.41 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 5β-Androst-1-ene-3,17-dione (C19H26O2) 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 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.

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.
