5-Fluoro-6-iodo-1-(triisopropylsilyl)-4-(trimethylsilyl)-1H-pyrrolo[2,3-b]pyridine CAS 1261365-70-1

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.

5-Fluoro-6-iodo-1-(triisopropylsilyl)-4-(trimethylsilyl)-1H-pyrrolo[2,3-b]pyridine (CAS 1261365-70-1) is a high-purity analytical reference standard with the molecular formula C19H32FIN2Si2 and a molecular weight of 490.54 g/mol.

5-Fluoro-6-iodo-1-(triisopropylsilyl)-4-(trimethylsilyl)-1H-pyrrolo[2,3-b]pyridine (C19H32FIN2Si2) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, fluorine/iodine 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.

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.
