3-(3,5-Dimethyl-4-(4-(pyridin-3-ylsulfonyl)piperazin-1-yl)-1H-pyrazol-1-yl)tetrahydrothiophene 1,1-dioxide CAS 1251564-48-3 chemical structure

Description

3-(3,5-Dimethyl-4-(4-(pyridin-3-ylsulfonyl)piperazin-1-yl)-1H-pyrazol-1-yl)tetrahydrothiophene 1,1-dioxide (CAS 1251564-48-3) is a high-purity analytical reference standard with the molecular formula C18H25N5O4S2 and a molecular weight of 439.55 g/mol.

The molecular framework of 3-(3,5-Dimethyl-4-(4-(pyridin-3-ylsulfonyl)piperazin-1-yl)-1H-pyrazol-1-yl)tetrahydrothiophene 1,1-dioxide (C18H25N5O4S2) is characterized by a flavonoid core, 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.
