Chemical Structure
Description
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.
(2-(4-Bromophenoxy)ethoxy)(tert-butyl)diphenylsilane (CAS 1704073-75-5) is a high-purity analytical reference standard with the molecular formula C24H27BrO2Si and a molecular weight of 455.46 g/mol.
(2-(4-Bromophenoxy)ethoxy)(tert-butyl)diphenylsilane (C24H27BrO2Si) contains a steroid core, a hydroxyl group, an ether linkage, bromine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
CATO manufactures (2-(4-Bromophenoxy)ethoxy)(tert-butyl)diphenylsilane 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.
