Description
As a certified reference material (CRM), cis-2-(3,5-Dimethylbenzoyl)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-2-(3,5-Dimethylbenzoyl)cyclohexane-1-carboxylic acid (CAS 733742-69-3) is a high-purity analytical reference standard with the molecular formula C16H20O3 and a molecular weight of 260.33 g/mol.
cis-2-(3,5-Dimethylbenzoyl)cyclohexane-1-carboxylic 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.
