Chemical Structure
Description
The molecular framework of 1,4,5,8-TETRAHYDROXYANTHRAQUINONE (C14H8O6) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system. 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 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).
1,4,5,8-TETRAHYDROXYANTHRAQUINONE (CAS 81-60-7), molecular formula C14H8O6 and molecular weight 272.21 g/mol, is a CATO reference standard with documented purity and traceability.
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), 1,4,5,8-TETRAHYDROXYANTHRAQUINONE 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.
