Chemical Structure
Description
The occurrence of 4-(bromomethyl)-3-(trifluoromethyl)-1-(triphenylmethyl)-1H-pyrazole is closely related to a nitrogen-containing heterocyclic scaffold, a nitrile group, fluorine/bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
4-(bromomethyl)-3-(trifluoromethyl)-1-(triphenylmethyl)-1H-pyrazole (CAS 928053-96-7), molecular formula C24H40BrF3N2 and molecular weight 493.49 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 4-(bromomethyl)-3-(trifluoromethyl)-1-(triphenylmethyl)-1H-pyrazole (C24H40BrF3N2) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, fluorine/bromine 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 4-(bromomethyl)-3-(trifluoromethyl)-1-(triphenylmethyl)-1H-pyrazole meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
