Chemical Structure
Description
Owing to a hydroxyl group, an ether linkage, fluorine/bromine substitution, an aromatic ring system, 1-Bromo-3-(tert-butoxy)-5-(trifluoromethyl)benzene is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 297.11 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).
1-Bromo-3-(tert-butoxy)-5-(trifluoromethyl)benzene (CAS 1369836-39-4), molecular formula C11H12BrF3O and molecular weight 297.11 g/mol, is a CATO reference standard with documented purity and traceability.
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.
