Chemical Structure
Description
3-Chloro-3,4,5-trifluorobenzophenone (CAS 951890-31-6) is a high-purity analytical reference standard with the molecular formula C13H6ClF3O and a molecular weight of 270.63 g/mol.
Structurally, 3-Chloro-3,4,5-trifluorobenzophenone (C13H6ClF3O) contains a hydroxyl group, an ether linkage, fluorine/chlorine substitution, an aromatic ring 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 270.63 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).
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.
As a certified reference material (CRM), 3-Chloro-3,4,5-trifluorobenzophenone 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.
