2-{[(4-Fluorophenyl)sulfonyl]amino}benzoic acid CAS 51012-30-7

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2-{[(4-Fluorophenyl)sulfonyl]amino}benzoic acid.

2-{[(4-Fluorophenyl)sulfonyl]amino}benzoic acid (CAS 51012-30-7), molecular formula C13H10FNO4S and molecular weight 295.29 g/mol, is a CATO reference standard with documented purity and traceability.

2-{[(4-Fluorophenyl)sulfonyl]amino}benzoic acid (C13H10FNO4S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone 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.

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.
