Chemical Structure
Description
(R)-4-(4-methyl-6-oxo-1,4,5,6-tetrahydropyridazin-3-yl)benzenediazonium tetrafluoroborate (CAS 1630761-22-6) is a high-purity analytical reference standard with the molecular formula C11H11N4OBF4 and a molecular weight of 302.04 g/mol.
(R)-4-(4-methyl-6-oxo-1,4,5,6-tetrahydropyridazin-3-yl)benzenediazonium tetrafluoroborate (C11H11N4OBF4) contains a nitrogen-containing heterocyclic scaffold, 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.
