Chemical Structure
Description
The occurrence of tert-Butyl(3-chloro-4-fluoro-5-(trifluoromethyl)phenoxy)dimethylsilane is closely related to a hydroxyl group, an ether linkage, fluorine/chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies tert-Butyl(3-chloro-4-fluoro-5-(trifluoromethyl)phenoxy)dimethylsilane (CAS 1881320-41-7), a certified reference material (molecular formula C13H17ClF4OSi, MW 328.81 g/mol) for analytical method development and quality control.
Owing to a hydroxyl group, an ether linkage, fluorine/chlorine substitution, tert-Butyl(3-chloro-4-fluoro-5-(trifluoromethyl)phenoxy)dimethylsilane is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 328.81 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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 tert-Butyl(3-chloro-4-fluoro-5-(trifluoromethyl)phenoxy)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.
