Chemical Structure
Description
As a certified reference material (CRM), 1-(2-((1-Ethyl-5-methyl-1H-pyrazol-4-yl)sulfonyl)ethyl)piperazine 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-((1-Ethyl-5-methyl-1H-pyrazol-4-yl)sulfonyl)ethyl)piperazine (CAS 1707370-10-2) is a high-purity analytical reference standard with the molecular formula C12H22N4O2S and a molecular weight of 286.39 g/mol.
The molecular framework of 1-(2-((1-Ethyl-5-methyl-1H-pyrazol-4-yl)sulfonyl)ethyl)piperazine (C12H22N4O2S) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
