1-(4-Fluorophenyl)-4-isopropyl-1H-pyrazolo[3,4-d]pyridazine-7-thiol CAS 1105198-06-8

Description

1-(4-Fluorophenyl)-4-isopropyl-1H-pyrazolo[3,4-d]pyridazine-7-thiol (C14H13FN4S) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, fluorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; 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.

1-(4-Fluorophenyl)-4-isopropyl-1H-pyrazolo[3,4-d]pyridazine-7-thiol (CAS 1105198-06-8) is a high-purity analytical reference standard with the molecular formula C14H13FN4S and a molecular weight of 288.34 g/mol.

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.
