Chemical Structure
Description
The occurrence of 6-Nitroquinolin-5-ol 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.
6-Nitroquinolin-5-ol (CAS 58416-46-9), molecular formula C9H6N2O3 and molecular weight 190.16 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 6-Nitroquinolin-5-ol (C9H6N2O3) 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), 6-Nitroquinolin-5-ol 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.
