Description

2-(2-Chloro-6-hydroxy-5-(((2-methylquinolin-8-yl)amino)methyl)-3-oxo-3H-xanthen-9-yl)benzoic acid (CAS 905982-78-7) is a high-purity analytical reference standard with the molecular formula C31H21ClN2O5 and a molecular weight of 536.96 g/mol.

2-(2-Chloro-6-hydroxy-5-(((2-methylquinolin-8-yl)amino)methyl)-3-oxo-3H-xanthen-9-yl)benzoic acid (C31H21ClN2O5) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine 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), 2-(2-Chloro-6-hydroxy-5-(((2-methylquinolin-8-yl)amino)methyl)-3-oxo-3H-xanthen-9-yl)benzoic acid 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.
