Chemical Structure
Description
3-(4-Chlorophenyl)-3-methylpropiophenone (CAS 898787-60-5), molecular formula C16H15ClO and molecular weight 258.74 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 3-(4-Chlorophenyl)-3-methylpropiophenone (C16H15ClO) is characterized by a hydroxyl group, an ether linkage, chlorine substitution, a polycyclic aromatic system. 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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-(4-Chlorophenyl)-3-methylpropiophenone 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.
