Chemical Structure
Description
CATO supplies 1-(3-Bromophenyl)-5-methyl-3-(trifluoromethyl)-1H-pyrazole (CAS 327046-86-6), a certified reference material (molecular formula C11H8BrF3N2, MW 305.09 g/mol) for analytical method development and quality control.
Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, fluorine/bromine substitution, 1-(3-Bromophenyl)-5-methyl-3-(trifluoromethyl)-1H-pyrazole is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 305.09 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO manufactures 1-(3-Bromophenyl)-5-methyl-3-(trifluoromethyl)-1H-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.
