Compared with other compounds in its class, the molecular weight of 258.31 g/mol gives 6-Benzoyl-3,4-dimethylcyclohex-3-ene-1-carboxylic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
6-Benzoyl-3,4-dimethylcyclohex-3-ene-1-carboxylic acid (CAS 93015-58-8), molecular formula C16H18O3 and molecular weight 258.31 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 6-Benzoyl-3,4-dimethylcyclohex-3-ene-1-carboxylic acid (C16H18O3) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
