Chemical Structure
Description
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.
CATO supplies 7-(1-((3-Chloro-5-(trifluoromethyl)pyridin-2-yl)thio)ethyl)pyrazolo[1,5-a]pyrimidine-3-carbonitrile (CAS 303151-82-8), a certified reference material (molecular formula C15H9ClF3N5S, MW 383.78 g/mol) for analytical method development and quality control.
The molecular framework of 7-(1-((3-Chloro-5-(trifluoromethyl)pyridin-2-yl)thio)ethyl)pyrazolo[1,5-a]pyrimidine-3-carbonitrile (C15H9ClF3N5S) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, fluorine/chlorine 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. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
