Chemical Structure
Description
(3E)-4-[3-(4-tert-Butylphenoxy)phenyl]but-3-en-2-one (C20H22O2) contains a steroid core, a hydroxyl group, an ether linkage. Its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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).
(3E)-4-[3-(4-tert-Butylphenoxy)phenyl]but-3-en-2-one (CAS 551930-90-6) is a high-purity analytical reference standard with the molecular formula C20H22O2 and a molecular weight of 294.39 g/mol.
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.
