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.
3,5-Dichloro-3-(4-fluorophenyl)propiophenone (CAS 898768-76-8), molecular formula C15H11Cl2FO and molecular weight 297.15 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 3,5-Dichloro-3-(4-fluorophenyl)propiophenone (C15H11Cl2FO) contains a hydroxyl group, an ether linkage, fluorine/chlorine substitution, a polycyclic aromatic system. The molecule exhibits a degree of unsaturation (DBE) of 9.0, corresponding to approximately 9 ring(s) or double-bond equivalent(s). With a molecular weight of 297.15 g/mol, it falls into the medium-molecular-weight range. 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).
As a certified reference material (CRM), 3,5-Dichloro-3-(4-fluorophenyl)propiophenone meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
