Chemical Structure

17-O-tert-Butyldimethylsilyl 5,14-Androstadiene-3β,17β-diol CAS 61252-32-2 chemical structure

Description

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.

17-O-tert-Butyldimethylsilyl 5,14-Androstadiene-3β,17β-diol (CAS 61252-32-2) is a high-purity analytical reference standard with the molecular formula C25H42O2Si and a molecular weight of 402.69 g/mol.

The molecular framework of 17-O-tert-Butyldimethylsilyl 5,14-Androstadiene-3β,17β-diol (C25H42O2Si) 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).

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
