1-(2,4-Dichlorobenzenesulfonyl)-5-[2-(1H-1,2,4-triazol-1-yl)propan-2-yl]-1H-pyrazole-4-carbonitrile CAS 318469-20-4

Description

As a certified reference material (CRM), 1-(2,4-Dichlorobenzenesulfonyl)-5-[2-(1H-1,2,4-triazol-1-yl)propan-2-yl]-1H-pyrazole-4-carbonitrile meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.

1-(2,4-Dichlorobenzenesulfonyl)-5-[2-(1H-1,2,4-triazol-1-yl)propan-2-yl]-1H-pyrazole-4-carbonitrile (CAS 318469-20-4), molecular formula C15H12Cl2N6O2S and molecular weight 411.27 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C15H12Cl2N6O2S, 1-(2,4-Dichlorobenzenesulfonyl)-5-[2-(1H-1,2,4-triazol-1-yl)propan-2-yl]-1H-pyrazole-4-carbonitrile 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 411.27 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.
