Description
Compared with other compounds in its class, the molecular weight of 339.36 g/mol gives 1-(Tert-butyl)-N-(4-methylbenzyl)-5-(trifluoromethyl)-1H-pyrazole-4-carboxamide distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
1-(Tert-butyl)-N-(4-methylbenzyl)-5-(trifluoromethyl)-1H-pyrazole-4-carboxamide (CAS 956370-20-0) is a high-purity analytical reference standard with the molecular formula C17H20F3N3O and a molecular weight of 339.36 g/mol.
The molecular framework of 1-(Tert-butyl)-N-(4-methylbenzyl)-5-(trifluoromethyl)-1H-pyrazole-4-carboxamide (C17H20F3N3O) is characterized by a steroid core, an amide 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.
