Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 275.30 g/mol gives 5-(Diethylsulfamoyl)-2-fluorobenzoic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
5-(Diethylsulfamoyl)-2-fluorobenzoic acid (CAS 61953-39-7), molecular formula C11H14FNO4S and molecular weight 275.30 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine substitution, 5-(Diethylsulfamoyl)-2-fluorobenzoic acid is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 275.30 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
