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 1-(2-Nitrophenyl)-1H-pyrrole-2,5-dione.
CATO supplies 1-(2-Nitrophenyl)-1H-pyrrole-2,5-dione (CAS 2973-15-1), a certified reference material (molecular formula C10H6N2O4, MW 218.17 g/mol) for analytical method development and quality control.
The molecular framework of 1-(2-Nitrophenyl)-1H-pyrrole-2,5-dione (C10H6N2O4) 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.
