6-(4-Methoxyphenyl)-3,7,8,10-tetraazatricyclo[7.4.0.0,2,7]trideca-1,3,5,8,10,12-hexaene-4-carboxylic acid (CAS 1574411-07-6), molecular formula C17H12N4O3 and molecular weight 320.30 g/mol, is a CATO reference standard with documented purity and traceability.
6-(4-Methoxyphenyl)-3,7,8,10-tetraazatricyclo[7.4.0.0,2,7]trideca-1,3,5,8,10,12-hexaene-4-carboxylic acid (C17H12N4O3) contains a steroid core, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, 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.
