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 4-[(8-Nitroquinolin-2-yl)amino]benzoic acid.
4-[(8-Nitroquinolin-2-yl)amino]benzoic acid (CAS 330663-19-9) is a high-purity analytical reference standard with the molecular formula C16H11N3O4 and a molecular weight of 309.28 g/mol.
Owing to a flavonoid core, an amide group, a hydroxyl group, an ether linkage, 4-[(8-Nitroquinolin-2-yl)amino]benzoic acid is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 309.28 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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 4-[(8-Nitroquinolin-2-yl)amino]benzoic acid 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.
