Chemical Structure
Description
Bis(4-acetamidophenyl) carbonate (CAS 19959-81-0), molecular formula C11H11N3O2 and molecular weight 217.22 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of Bis(4-acetamidophenyl) carbonate (C11H11N3O2) is characterized by an amino-acid-derived structure, 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.
As a certified reference material (CRM), Bis(4-acetamidophenyl) carbonate 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.
