Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2-(2-(4-Chlorophenyl)-2-oxoethyl)-5,5-dimethylcyclohexane-1,3-dione.
CATO supplies 2-(2-(4-Chlorophenyl)-2-oxoethyl)-5,5-dimethylcyclohexane-1,3-dione (CAS 242151-13-9), a certified reference material (molecular formula C16H17ClO3, MW 292.76 g/mol) for analytical method development and quality control.
The molecular framework of 2-(2-(4-Chlorophenyl)-2-oxoethyl)-5,5-dimethylcyclohexane-1,3-dione (C16H17ClO3) is characterized by a carboxylic acid group, 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), 2-(2-(4-Chlorophenyl)-2-oxoethyl)-5,5-dimethylcyclohexane-1,3-dione 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.
