2-[(1Z)-1-Cyano-2-(dimethylamino)eth-1-en-1-yl]-5,7-bis(trifluoromethyl)pyrazolo[1,5-a]pyrimidine-3-carbonitrile CAS 338786-57-5 chemical structure

Description

2-[(1Z)-1-Cyano-2-(dimethylamino)eth-1-en-1-yl]-5,7-bis(trifluoromethyl)pyrazolo[1,5-a]pyrimidine-3-carbonitrile (C14H8F6N6) 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

2-[(1Z)-1-Cyano-2-(dimethylamino)eth-1-en-1-yl]-5,7-bis(trifluoromethyl)pyrazolo[1,5-a]pyrimidine-3-carbonitrile (CAS 338786-57-5), molecular formula C14H8F6N6 and molecular weight 374.24 g/mol, is a CATO reference standard with documented purity and traceability.

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.

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.
