Compared with other compounds in its class, the molecular weight of 260.33 g/mol gives trans-4-(2-Oxo-2-(o-tolyl)ethyl)cyclohexanecarboxylic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies trans-4-(2-Oxo-2-(o-tolyl)ethyl)cyclohexanecarboxylic acid (CAS 735275-75-9), a certified reference material (molecular formula C16H20O3, MW 260.33 g/mol) for analytical method development and quality control.
trans-4-(2-Oxo-2-(o-tolyl)ethyl)cyclohexanecarboxylic acid (C16H20O3) contains a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system. Its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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), trans-4-(2-Oxo-2-(o-tolyl)ethyl)cyclohexanecarboxylic 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.
