Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Diphenyl 1H-benzo[d]imidazol-2-ylphosphoramidate.
Diphenyl 1H-benzo[d]imidazol-2-ylphosphoramidate (CAS 882865-02-3), molecular formula C19H16N3O3P and molecular weight 365.32 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of Diphenyl 1H-benzo[d]imidazol-2-ylphosphoramidate (C19H16N3O3P) is characterized by a steroid core, an amide group, a phosphonate 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), Diphenyl 1H-benzo[d]imidazol-2-ylphosphoramidate 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.
