Chemical Structure
Description
tert-Butyl 4-((4-bromo-2-fluorobenzyl)oxy)piperidine-1-carboxylate (CAS 1704095-50-0), molecular formula C17H23BrFNO3 and molecular weight 388.27 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of tert-Butyl 4-((4-bromo-2-fluorobenzyl)oxy)piperidine-1-carboxylate (C17H23BrFNO3) is characterized by a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine/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. 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.
CATO manufactures tert-Butyl 4-((4-bromo-2-fluorobenzyl)oxy)piperidine-1-carboxylate under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
