3-((((9H-Fluoren-9-yl)methoxy)carbonyl)amino)-2-fluorobenzoic acid CAS 1881771-89-6

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 3-((((9H-Fluoren-9-yl)methoxy)carbonyl)amino)-2-fluorobenzoic acid.

3-((((9H-Fluoren-9-yl)methoxy)carbonyl)amino)-2-fluorobenzoic acid (CAS 1881771-89-6) is a high-purity analytical reference standard with the molecular formula C22H16FNO4 and a molecular weight of 377.37 g/mol.

3-((((9H-Fluoren-9-yl)methoxy)carbonyl)amino)-2-fluorobenzoic acid (C22H16FNO4) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. 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.

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

CATO manufactures 3-((((9H-Fluoren-9-yl)methoxy)carbonyl)amino)-2-fluorobenzoic 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.
