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.
(2E)-3-[4-(Benzyloxy)phenyl]-1-(2-methoxyphenyl)prop-2-en-1-one (CAS 906635-45-8), molecular formula C23H20O3 and molecular weight 344.40 g/mol, is a CATO reference standard with documented purity and traceability.
(2E)-3-[4-(Benzyloxy)phenyl]-1-(2-methoxyphenyl)prop-2-en-1-one (C23H20O3) 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
