(1S,2S)-2-(4-bromobenzoyl)cyclohexane-1-carboxylic acid (CAS 2305050-56-8), molecular formula C14H15BrO3 and molecular weight 311.17 g/mol, is a CATO reference standard with documented purity and traceability.
(1S,2S)-2-(4-bromobenzoyl)cyclohexane-1-carboxylic acid (C14H15BrO3) contains a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution, a polycyclic aromatic system. It is notably hygroscopic, halogen substitution raises its density and boiling point, 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).
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.
