Chemical Structure

tert-Butyl(4-(chloromethyl)phenoxy)dimethylsilane CAS 138585-09-8 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.

CATO supplies tert-Butyl(4-(chloromethyl)phenoxy)dimethylsilane (CAS 138585-09-8), a certified reference material (molecular formula C13H21ClOSi, MW 256.84 g/mol) for analytical method development and quality control.

tert-Butyl(4-(chloromethyl)phenoxy)dimethylsilane (C13H21ClOSi) contains a hydroxyl group, an ether linkage, chlorine 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.

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.
