Description
As a certified reference material (CRM), 11-(3,4-Dimethoxyphenyl)-6-hydroxy-8-thia-3,5,10-triazatricyclo[7.4.0.0^{2,7}]trideca-1(9),2(7),5,10,12-pentaen-4-one 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.
CATO supplies 11-(3,4-Dimethoxyphenyl)-6-hydroxy-8-thia-3,5,10-triazatricyclo[7.4.0.0^{2,7}]trideca-1(9),2(7),5,10,12-pentaen-4-one (CAS 665001-01-4), a certified reference material (molecular formula C17H13N3O4S, MW 355.37 g/mol) for analytical method development and quality control.
The molecular framework of 11-(3,4-Dimethoxyphenyl)-6-hydroxy-8-thia-3,5,10-triazatricyclo[7.4.0.0^{2,7}]trideca-1(9),2(7),5,10,12-pentaen-4-one (C17H13N3O4S) is characterized by a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
