Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 7-[4-(1H-1,2,4-Triazol-1-yl)phenyl]pyrazolo[1,5-a]pyrimidine-3-carbonitrile.
7-[4-(1H-1,2,4-Triazol-1-yl)phenyl]pyrazolo[1,5-a]pyrimidine-3-carbonitrile (CAS 866049-77-6), molecular formula C15H9N7 and molecular weight 287.28 g/mol, is a CATO reference standard with documented purity and traceability.
7-[4-(1H-1,2,4-Triazol-1-yl)phenyl]pyrazolo[1,5-a]pyrimidine-3-carbonitrile (C15H9N7) contains a nitrogen-containing heterocyclic scaffold, a nitrile group. Its physicochemical properties are representative of its class; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
