Chemical Structure
Description
The molecular framework of 3-Iodo-5-phenyl-1H-pyrrolo[2,3-b]pyridine (C13H9IN2) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, iodine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
3-Iodo-5-phenyl-1H-pyrrolo[2,3-b]pyridine (CAS 757982-79-9), molecular formula C13H9IN2 and molecular weight 320.13 g/mol, is a CATO reference standard with documented purity and traceability.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 3-Iodo-5-phenyl-1H-pyrrolo[2,3-b]pyridine meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
