Description
CATO supplies 3,5-Dimethyl-1-{2-[1-methyl-5-(trifluoromethyl)-1H-pyrazol-4-yl]-7-phenylpyrazolo[1,5-a]pyrimidin-6-yl}-1H-pyrazole (CAS 956502-21-9), a certified reference material (molecular formula C22H18F3N7, MW 437.42 g/mol) for analytical method development and quality control.
The molecular framework of 3,5-Dimethyl-1-{2-[1-methyl-5-(trifluoromethyl)-1H-pyrazol-4-yl]-7-phenylpyrazolo[1,5-a]pyrimidin-6-yl}-1H-pyrazole (C22H18F3N7) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, fluorine 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), 3,5-Dimethyl-1-{2-[1-methyl-5-(trifluoromethyl)-1H-pyrazol-4-yl]-7-phenylpyrazolo[1,5-a]pyrimidin-6-yl}-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.
