Chemical Structure
Description
1-(2-Bromo-5-fluorobenzyl)-4-((tert-butyldimethylsilyl)oxy)piperidine (CAS 1704065-57-5) is a high-purity analytical reference standard with the molecular formula C18H29BrFNOSi and a molecular weight of 402.42 g/mol.
1-(2-Bromo-5-fluorobenzyl)-4-((tert-butyldimethylsilyl)oxy)piperidine (C18H29BrFNOSi) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine/bromine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
As a certified reference material (CRM), 1-(2-Bromo-5-fluorobenzyl)-4-((tert-butyldimethylsilyl)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.
