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.
4-(2-(2-(4-Chlorophenyl)-1H-indol-3-yl)hydrazinyl)-N-(4,6-dimethylpyrimidin-2-yl)benzenesulfonamide (CAS 88152-04-9) is a high-purity analytical reference standard with the molecular formula C26H23ClN6O2S and a molecular weight of 519.02 g/mol.
Based on its molecular formula C26H23ClN6O2S, 4-(2-(2-(4-Chlorophenyl)-1H-indol-3-yl)hydrazinyl)-N-(4,6-dimethylpyrimidin-2-yl)benzenesulfonamide contains a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 519.02 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).
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.
