Chemical Structure

cis-4-[2-Oxo-2-(2-trifluoromethylphenyl)-ethyl]cyclohexane-1-carboxylic acid CAS 735275-68-0 chemical structure

Description

As a certified reference material (CRM), cis-4-[2-Oxo-2-(2-trifluoromethylphenyl)-ethyl]cyclohexane-1-carboxylic acid 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.

cis-4-[2-Oxo-2-(2-trifluoromethylphenyl)-ethyl]cyclohexane-1-carboxylic acid (CAS 735275-68-0), molecular formula C16H17F3O3 and molecular weight 314.30 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of cis-4-[2-Oxo-2-(2-trifluoromethylphenyl)-ethyl]cyclohexane-1-carboxylic acid (C16H17F3O3) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine 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.
