Chemical Structure
Description
2-[({[5-(dimethylsulfamoyl)-2-methylphenyl]carbamoyl}methyl)sulfanyl]pyridine-3-carboxylic acid (CAS 725716-30-3) is a high-purity analytical reference standard with the molecular formula C17H19N3O5S2 and a molecular weight of 409.48 g/mol.
Based on its molecular formula C17H19N3O5S2, 2-[({[5-(dimethylsulfamoyl)-2-methylphenyl]carbamoyl}methyl)sulfanyl]pyridine-3-carboxylic acid contains a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 409.48 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
