Chemical Structure
Description
The occurrence of 1-(2-(4-Bromo-2-fluorophenoxy)ethyl)-4-((tert-butyldiphenylsilyl)oxy)piperidine is closely related to a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine/bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
1-(2-(4-Bromo-2-fluorophenoxy)ethyl)-4-((tert-butyldiphenylsilyl)oxy)piperidine (CAS 1704082-78-9), molecular formula C29H35BrFNO2Si and molecular weight 556.58 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine/bromine substitution, 1-(2-(4-Bromo-2-fluorophenoxy)ethyl)-4-((tert-butyldiphenylsilyl)oxy)piperidine is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 556.58 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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), 1-(2-(4-Bromo-2-fluorophenoxy)ethyl)-4-((tert-butyldiphenylsilyl)oxy)piperidine 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.
