Description
As a certified reference material (CRM), 3-(4-Nitro-1,3-dioxoisoindolin-2-yl)benzoic acid 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.
3-(4-Nitro-1,3-dioxoisoindolin-2-yl)benzoic acid (CAS 300405-52-1), molecular formula C15H8N2O6 and molecular weight 312.23 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 3-(4-Nitro-1,3-dioxoisoindolin-2-yl)benzoic acid (C15H8N2O6) is characterized by a flavonoid core, an amide 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.
