1-((2,4-Dichloro-5-methylphenyl)sulfonyl)-4-(2-hydroxyethyl)-5-methyl-1,2-dihydro-3H-pyrazol-3-one CAS 861207-41-2

Description

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.

1-((2,4-Dichloro-5-methylphenyl)sulfonyl)-4-(2-hydroxyethyl)-5-methyl-1,2-dihydro-3H-pyrazol-3-one (CAS 861207-41-2) is a high-purity analytical reference standard with the molecular formula C13H14Cl2N2O4S and a molecular weight of 365.23 g/mol.

Based on its molecular formula C13H14Cl2N2O4S, 1-((2,4-Dichloro-5-methylphenyl)sulfonyl)-4-(2-hydroxyethyl)-5-methyl-1,2-dihydro-3H-pyrazol-3-one contains a nitrogen-containing heterocyclic scaffold, 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 365.23 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
