3-(Tert-butylsulfamoyl)-4-fluorobenzoic acid CAS 926245-18-3

Description

Compared with other compounds in its class, the molecular weight of 275.30 g/mol gives 3-(Tert-butylsulfamoyl)-4-fluorobenzoic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

3-(Tert-butylsulfamoyl)-4-fluorobenzoic acid (CAS 926245-18-3) is a high-purity analytical reference standard with the molecular formula C11H14FNO4S and a molecular weight of 275.30 g/mol.

The molecular framework of 3-(Tert-butylsulfamoyl)-4-fluorobenzoic acid (C11H14FNO4S) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
