Chemical Structure
Description
The occurrence of 5-Nitro-2-phenylpyrimidine-4,6-diamine is closely related to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 5-Nitro-2-phenylpyrimidine-4,6-diamine (CAS 3346-20-1), a certified reference material (molecular formula C10H9N5O2, MW 231.21 g/mol) for analytical method development and quality control.
The molecular framework of 5-Nitro-2-phenylpyrimidine-4,6-diamine (C10H9N5O2) 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), 5-Nitro-2-phenylpyrimidine-4,6-diamine 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.
