2-[(1Z)-1-Cyano-2-phenyleth-1-en-1-yl]-5,7-bis(trifluoromethyl)pyrazolo[1,5-a]pyrimidine-3-carbonitrile CAS 338786-53-1

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 2-[(1Z)-1-Cyano-2-phenyleth-1-en-1-yl]-5,7-bis(trifluoromethyl)pyrazolo[1,5-a]pyrimidine-3-carbonitrile (CAS 338786-53-1), a certified reference material (molecular formula C18H7F6N5, MW 407.27 g/mol) for analytical method development and quality control.

The molecular framework of 2-[(1Z)-1-Cyano-2-phenyleth-1-en-1-yl]-5,7-bis(trifluoromethyl)pyrazolo[1,5-a]pyrimidine-3-carbonitrile (C18H7F6N5) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, fluorine 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
