n-(4-Chloro-1-ethyl-3-methyl-1h-pyrazol-5-yl)methanesulfonamide (CAS 1484641-23-7) is a high-purity analytical reference standard with the molecular formula C7H12ClN3O2S and a molecular weight of 237.71 g/mol.
The molecular framework of n-(4-Chloro-1-ethyl-3-methyl-1h-pyrazol-5-yl)methanesulfonamide (C7H12ClN3O2S) is characterized by an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine 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. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
