Chemical Structure
Description
5-Fluoro-3-iodo-1-[tris(propan-2-yl)silyl]-1H-pyrrolo[2,3-b]pyridine (CAS 928653-76-3) is a high-purity analytical reference standard with the molecular formula C16H24FIN2Si and a molecular weight of 418.36 g/mol.
Structurally, 5-Fluoro-3-iodo-1-[tris(propan-2-yl)silyl]-1H-pyrrolo[2,3-b]pyridine (C16H24FIN2Si) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, fluorine/iodine substitution. The molecule exhibits a degree of unsaturation (DBE) of 5.0, corresponding to approximately 5 ring(s) or double-bond equivalent(s). With a molecular weight of 418.36 g/mol, it falls into the moderately-high-molecular-weight range. 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.
CATO manufactures 5-Fluoro-3-iodo-1-[tris(propan-2-yl)silyl]-1H-pyrrolo[2,3-b]pyridine under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
