Chemical Structure

Testosterone-17-sulfate CAS 651-45-6 chemical structure

Description

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.

CATO supplies Testosterone-17-sulfate (CAS 651-45-6), a certified reference material (molecular formula C19H28O5S, MW 368.49 g/mol) for analytical method development and quality control.

Based on its molecular formula C19H28O5S, Testosterone-17-sulfate contains a steroid core, a sulfone group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 368.49 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
