11,13-dimethyl-4,5,7,11,13-pentaazatricyclo[7.4.0.0^{2,6}]trideca-1(9),2(6),3,7-tetraene-10,12-dione CAS 1989659-57-5

Description

11,13-dimethyl-4,5,7,11,13-pentaazatricyclo[7.4.0.0^{2,6}]trideca-1(9),2(6),3,7-tetraene-10,12-dione (CAS 1989659-57-5), molecular formula C10H9N5O2 and molecular weight 231.21 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, 11,13-dimethyl-4,5,7,11,13-pentaazatricyclo[7.4.0.0^{2,6}]trideca-1(9),2(6),3,7-tetraene-10,12-dione is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 231.21 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.

As a certified reference material (CRM), 11,13-dimethyl-4,5,7,11,13-pentaazatricyclo[7.4.0.0^{2,6}]trideca-1(9),2(6),3,7-tetraene-10,12-dione 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.
