Chemical Structure
Description
CATO supplies (2E)-1-(2,5-Dichlorophenyl)-3-(2-methylphenyl)prop-2-en-1-one (CAS 569325-93-5), a certified reference material (molecular formula C16H12Cl2O, MW 291.17 g/mol) for analytical method development and quality control.
Structurally, (2E)-1-(2,5-Dichlorophenyl)-3-(2-methylphenyl)prop-2-en-1-one (C16H12Cl2O) contains a hydroxyl group, an ether linkage, chlorine substitution, a polycyclic aromatic system. The molecule exhibits a degree of unsaturation (DBE) of 10.0, corresponding to approximately 10 ring(s) or double-bond equivalent(s). With a molecular weight of 291.17 g/mol, it falls into the medium-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
