CATO manufactures 3,5-Dimethyl-1-phenyl-4-(phenylthio)-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.

3,5-Dimethyl-1-phenyl-4-(phenylthio)-1H-pyrazole (CAS 245725-85-3), molecular formula C17H16N2S and molecular weight 280.39 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 3,5-Dimethyl-1-phenyl-4-(phenylthio)-1H-pyrazole (C17H16N2S) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality. 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. 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.
