Chemical Structure
Description
1-Hydroxy-2-nitroanthracene-9,10-dione (CAS 5227-66-7), molecular formula C14H7NO5 and molecular weight 269.21 g/mol, is a CATO reference standard with documented purity and traceability.
1-Hydroxy-2-nitroanthracene-9,10-dione (C14H7NO5) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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-Hydroxy-2-nitroanthracene-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.
