Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies 3,3-Difluoro-1-(4-fluoro-2-(trifluoromethyl)-phenyl)pyrrolidine 1779132-20-5 (CAS 1779132-20-5), a certified reference material (molecular formula C11H9F6N, MW 269.19 g/mol) for analytical method development and quality control.
Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, fluorine substitution, 3,3-Difluoro-1-(4-fluoro-2-(trifluoromethyl)-phenyl)pyrrolidine 1779132-20-5 is typically off-white to pale yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 269.19 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).
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.
