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 7-Fluoro-6-nitro-1,2,3,4-tetrahydroquinolin-2-one.
CATO supplies 7-Fluoro-6-nitro-1,2,3,4-tetrahydroquinolin-2-one (CAS 1146289-84-0), a certified reference material (molecular formula C9H7FN2O3, MW 210.16 g/mol) for analytical method development and quality control.
7-Fluoro-6-nitro-1,2,3,4-tetrahydroquinolin-2-one (C9H7FN2O3) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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), 7-Fluoro-6-nitro-1,2,3,4-tetrahydroquinolin-2-one 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.
