Chemical Structure
Description
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.
Potassium 4-chloro-3-[(2-methoxy-5-nitrophenyl)sulfamoyl]benzoate (CAS 1007190-15-9), molecular formula C14H10ClN2O7SK and molecular weight 424.85 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a salt form, a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution, Potassium 4-chloro-3-[(2-methoxy-5-nitrophenyl)sulfamoyl]benzoate is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 424.85 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
