Chemical Structure
Description
The molecular framework of 1-(2-(4-Bromo-2-chlorophenoxy)ethyl)-4-((tert-butyldiphenylsilyl)oxy)piperidine (C29H35BrClNO2Si) is characterized by a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine/bromine substitution. 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).
1-(2-(4-Bromo-2-chlorophenoxy)ethyl)-4-((tert-butyldiphenylsilyl)oxy)piperidine (CAS 1704080-89-6) is a high-purity analytical reference standard with the molecular formula C29H35BrClNO2Si and a molecular weight of 573.04 g/mol.
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.
