Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
5-Bromo-2-chlorophenoxy(tert-butyl)dimethylsilane (CAS 1881291-40-2), molecular formula C12H18BrClOSi and molecular weight 321.71 g/mol, is a CATO reference standard with documented purity and traceability.
5-Bromo-2-chlorophenoxy(tert-butyl)dimethylsilane (C12H18BrClOSi) contains a hydroxyl group, an ether linkage, chlorine/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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
As a certified reference material (CRM), 5-Bromo-2-chlorophenoxy(tert-butyl)dimethylsilane 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.
