Chemical Structure

(4-Bromo-3-chlorophenoxy)(tert-butyl)dimethylsilane CAS 179120-53-7 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (4-Bromo-3-chlorophenoxy)(tert-butyl)dimethylsilane.

CATO supplies (4-Bromo-3-chlorophenoxy)(tert-butyl)dimethylsilane (CAS 179120-53-7), a certified reference material (molecular formula C12H18BrClOSi, MW 321.71 g/mol) for analytical method development and quality control.

Owing to a hydroxyl group, an ether linkage, chlorine/bromine substitution, (4-Bromo-3-chlorophenoxy)(tert-butyl)dimethylsilane is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 321.71 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
