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-(2-Bromo-6-methoxy-3,4-dihydronaphthalen-1-yl)phenoxy)(tert-butyl)dimethylsilane.
CATO supplies (4-(2-Bromo-6-methoxy-3,4-dihydronaphthalen-1-yl)phenoxy)(tert-butyl)dimethylsilane (CAS 2740660-49-3), a certified reference material (molecular formula C23H29BrO2Si, MW 445.46 g/mol) for analytical method development and quality control.
Owing to a steroid core, a hydroxyl group, an ether linkage, bromine substitution, (4-(2-Bromo-6-methoxy-3,4-dihydronaphthalen-1-yl)phenoxy)(tert-butyl)dimethylsilane is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 445.46 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.
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.
