Chemical Structure
Description
CATO supplies 4-(bromomethyl)-1-(trifluoromethyl)-1H-pyrazole (CAS 2169440-61-1), a certified reference material (molecular formula C5H8BrF3N2, MW 233.03 g/mol) for analytical method development and quality control.
The molecular framework of 4-(bromomethyl)-1-(trifluoromethyl)-1H-pyrazole (C5H8BrF3N2) is characterized by fluorine/bromine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, 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)-1-(trifluoromethyl)-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.
