Chemical Structure
Description
Owing to a hydroxyl group, an ether linkage, fluorine/chlorine substitution, a polycyclic aromatic system, 2,5-Dichloro-3-(3,4,5-trifluorophenyl)-propiophenone is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 333.13 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
2,5-Dichloro-3-(3,4,5-trifluorophenyl)-propiophenone (CAS 898778-56-8), molecular formula C15H9Cl2F3O and molecular weight 333.13 g/mol, is a CATO reference standard with documented purity and traceability.
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.
