Chemical Structure
Description
(E)-2-(4-((4-Butylphenyl)diazenyl)phenoxy)-N,N,N-trimethylethanaminium bromide (CAS 173450-00-5) is a high-purity analytical reference standard with the molecular formula C21H30N3OBr and a molecular weight of 420.39 g/mol.
Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, bromine substitution, (E)-2-(4-((4-Butylphenyl)diazenyl)phenoxy)-N,N,N-trimethylethanaminium bromide is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 420.39 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.
