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-({[(9H-Fluoren-9-yl)methoxy]carbonyl}amino)-5-iodobenzoic acid.
CATO supplies 3-({[(9H-Fluoren-9-yl)methoxy]carbonyl}amino)-5-iodobenzoic acid (CAS 1877666-09-5), a certified reference material (molecular formula C22H16INO4, MW 485.27 g/mol) for analytical method development and quality control.
3-({[(9H-Fluoren-9-yl)methoxy]carbonyl}amino)-5-iodobenzoic acid (C22H16INO4) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage, iodine 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.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
