Chemical Structure
Description
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.
CATO supplies (E)-6-(2-((2,4-difluorophenyl)amino)vinyl)pyrazolo[1,5-a]pyrido[3,4-e]pyrimidine-3-carbonitrile (CAS 338411-69-1), a certified reference material (molecular formula C18H10F2N6, MW 348.31 g/mol) for analytical method development and quality control.
Structurally, (E)-6-(2-((2,4-difluorophenyl)amino)vinyl)pyrazolo[1,5-a]pyrido[3,4-e]pyrimidine-3-carbonitrile (C18H10F2N6) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, fluorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 16.0, corresponding to approximately 16 ring(s) or double-bond equivalent(s). With a molecular weight of 348.31 g/mol, it falls into the moderately-high-molecular-weight range. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
