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 3-((4-Fluorophenyl)amino)-4-nitropyridine 1-oxide.
CATO supplies 3-((4-Fluorophenyl)amino)-4-nitropyridine 1-oxide (CAS 99822-90-9), a certified reference material (molecular formula C11H8FN3O3, MW 249.20 g/mol) for analytical method development and quality control.
3-((4-Fluorophenyl)amino)-4-nitropyridine 1-oxide (C11H8FN3O3) 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.
CATO manufactures 3-((4-Fluorophenyl)amino)-4-nitropyridine 1-oxide under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
