Chemical Structure
Description
The molecular framework of 4-Chloro-5-fluoro-1H-pyrrolo[2,3-b]pyridine 882033-66-1 C7H4ClFN2 Y5601 (C7H12ClFN2) is characterized by a nitrile group, fluorine/chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, 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.
4-Chloro-5-fluoro-1H-pyrrolo[2,3-b]pyridine 882033-66-1 C7H4ClFN2 Y5601 (CAS 882033-66-1) is a high-purity analytical reference standard with the molecular formula C7H12ClFN2 and a molecular weight of 178.63 g/mol.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
