3,5-dimethyl-8-oxo-1,3,4,7,12-pentaazatricyclo[7.3.0.0²,⁶]dodeca-2(6),4,9,11-tetraene-10-carboxylic acid (CAS 66825-92-1), molecular formula C10H9N5O3 and molecular weight 247.21 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage, 3,5-dimethyl-8-oxo-1,3,4,7,12-pentaazatricyclo[7.3.0.0²,⁶]dodeca-2(6),4,9,11-tetraene-10-carboxylic acid is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 247.21 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
