Chemical Structure
Description
(R)-(2-Bromo-1-(2-fluorophenyl)ethoxy)(tert-butyl)dimethylsilane (CAS 1263284-18-9), molecular formula C14H22BrFOSi and molecular weight 333.31 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, (R)-(2-Bromo-1-(2-fluorophenyl)ethoxy)(tert-butyl)dimethylsilane (C14H22BrFOSi) contains a hydroxyl group, an ether linkage, fluorine/bromine substitution. The molecule exhibits a degree of unsaturation (DBE) of 3.0, corresponding to approximately 3 ring(s) or double-bond equivalent(s). With a molecular weight of 333.31 g/mol, it falls into the moderately-high-molecular-weight range. 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).
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 (R)-(2-Bromo-1-(2-fluorophenyl)ethoxy)(tert-butyl)dimethylsilane 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.
