Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 240.25 g/mol gives 4-(3-Fluorophenyl)-3-(methylsulfonyl)-1H-pyrazole distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
4-(3-Fluorophenyl)-3-(methylsulfonyl)-1H-pyrazole (CAS 1710302-33-2), molecular formula C10H9FN2O2S and molecular weight 240.25 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 4-(3-Fluorophenyl)-3-(methylsulfonyl)-1H-pyrazole (C10H9FN2O2S) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine substitution. 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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO manufactures 4-(3-Fluorophenyl)-3-(methylsulfonyl)-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.
