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 4-(Azetidin-3-yl)-2-(trifluoromethyl)pyridine (CAS 2159739-48-5), a certified reference material (molecular formula C9H9F3N2, MW 202.18 g/mol) for analytical method development and quality control.
4-(Azetidin-3-yl)-2-(trifluoromethyl)pyridine (C9H9F3N2) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, fluorine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
