Description
Compared with other compounds in its class, the molecular weight of 381.20 g/mol gives 5-[(2,4-Dichlorophenoxy)methyl]-1-methyl-3-(trifluoromethyl)-1H-thieno[2,3-c]pyrazole distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
5-[(2,4-Dichlorophenoxy)methyl]-1-methyl-3-(trifluoromethyl)-1H-thieno[2,3-c]pyrazole (CAS 478031-76-4), molecular formula C14H9Cl2F3N2OS and molecular weight 381.20 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 5-[(2,4-Dichlorophenoxy)methyl]-1-methyl-3-(trifluoromethyl)-1H-thieno[2,3-c]pyrazole (C14H9Cl2F3N2OS) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, fluorine/chlorine 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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 5-[(2,4-Dichlorophenoxy)methyl]-1-methyl-3-(trifluoromethyl)-1H-thieno[2,3-c]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.
