3-(Benzo[d][1,3]dioxol-5-yl)-6-chloro-[1,2,4]triazolo[4,3-b]pyridazine CAS 448190-45-2

Description

Compared with other compounds in its class, the molecular weight of 274.66 g/mol gives 3-(Benzo[d][1,3]dioxol-5-yl)-6-chloro-[1,2,4]triazolo[4,3-b]pyridazine distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

3-(Benzo[d][1,3]dioxol-5-yl)-6-chloro-[1,2,4]triazolo[4,3-b]pyridazine (CAS 448190-45-2) is a high-purity analytical reference standard with the molecular formula C12H7ClN4O2 and a molecular weight of 274.66 g/mol.

3-(Benzo[d][1,3]dioxol-5-yl)-6-chloro-[1,2,4]triazolo[4,3-b]pyridazine (C12H7ClN4O2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; 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.
