Chemical Structure
Description
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.
(2E)-1-{[1,1'-Biphenyl]-4-yl}-3-(3-methylphenyl)prop-2-en-1-one (CAS 13662-57-2), molecular formula C22H18O and molecular weight 298.38 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of (2E)-1-{[1,1'-Biphenyl]-4-yl}-3-(3-methylphenyl)prop-2-en-1-one (C22H18O) is characterized by a steroid core, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
