5-Chloro-2-iodo-1-methyl-1H-pyrrolo[2,3-c]pyridine (CAS 2767307-59-3), molecular formula C8H6ClIN2 and molecular weight 292.50 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 5-Chloro-2-iodo-1-methyl-1H-pyrrolo[2,3-c]pyridine (C8H6ClIN2) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine/iodine 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
