Chemical Structure
Description
Structurally, 2-[(1Z)-1-Cyano-2-(pyridin-2-yl)eth-1-en-1-yl]-5,7-dimethylpyrazolo[1,5-a]pyrimidine-3-carbonitrile (C17H12N6) contains a nitrogen-containing heterocyclic scaffold, a nitrile group. The molecule exhibits a degree of unsaturation (DBE) of 15.0, corresponding to approximately 15 ring(s) or double-bond equivalent(s). With a molecular weight of 300.32 g/mol, it falls into the moderately-high-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
2-[(1Z)-1-Cyano-2-(pyridin-2-yl)eth-1-en-1-yl]-5,7-dimethylpyrazolo[1,5-a]pyrimidine-3-carbonitrile (CAS 338418-44-3), molecular formula C17H12N6 and molecular weight 300.32 g/mol, is a CATO reference standard with documented purity and traceability.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
