Chemical Structure
Description
CATO supplies 3-(4-Trifluoromethylphenyl)pyrazole (CAS 625-59-2), a certified reference material (molecular formula C14H14ClN5, MW 287.75 g/mol) for analytical method development and quality control.
Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution, 3-(4-Trifluoromethylphenyl)pyrazole is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 287.75 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
