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.
7-Amino-3-ethyl-4-oxo-1,4-dihydropyrazolo[5,1-c][1,2,4]triazine-8-carbonitrile (CAS 1351393-11-7), molecular formula C8H8N6O and molecular weight 204.19 g/mol, is a CATO reference standard with documented purity and traceability.
7-Amino-3-ethyl-4-oxo-1,4-dihydropyrazolo[5,1-c][1,2,4]triazine-8-carbonitrile (C8H8N6O) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. 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).
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.
