Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1,3,6,8-Tetramethoxyanthracene-9,10-dione.
1,3,6,8-Tetramethoxyanthracene-9,10-dione (CAS 2476-76-8), molecular formula C18H16O6 and molecular weight 328.32 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 1,3,6,8-Tetramethoxyanthracene-9,10-dione (C18H16O6) is characterized by a flavonoid core, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional 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.
As a certified reference material (CRM), 1,3,6,8-Tetramethoxyanthracene-9,10-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.
