Chemical Structure
Description
4-(Diethylamino)-2-(3-fluorophenyl)pyrazolo[1,5-a]pyrazine-3-carbaldehyde (CAS 1710833-92-3), molecular formula C17H17FN4O and molecular weight 312.34 g/mol, is a CATO reference standard with documented purity and traceability.
4-(Diethylamino)-2-(3-fluorophenyl)pyrazolo[1,5-a]pyrazine-3-carbaldehyde (C17H17FN4O) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, 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.
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.
