Description

Compared with other compounds in its class, the molecular weight of 250.32 g/mol gives 4-(Ethylsulfonyl)-3-(p-tolyl)-1H-pyrazole distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

4-(Ethylsulfonyl)-3-(p-tolyl)-1H-pyrazole (CAS 1707370-15-7), molecular formula C12H14N2O2S and molecular weight 250.32 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 4-(Ethylsulfonyl)-3-(p-tolyl)-1H-pyrazole (C12H14N2O2S) 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 its high hydrophobicity (logP), 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.

CATO manufactures 4-(Ethylsulfonyl)-3-(p-tolyl)-1H-pyrazole under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
