Chemical Structure

5beta-Dihydrotestosterone CAS 571-22-2 chemical structure

Description

The molecular framework of 5beta-Dihydrotestosterone (C19H30O2) 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).

CATO supplies 5beta-Dihydrotestosterone (CAS 571-22-2), a certified reference material (molecular formula C19H30O2, MW 290.44 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.

As a certified reference material (CRM), 5beta-Dihydrotestosterone 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.
