7-Chloro-4-iodo-3-methyl-1H-pyrrolo[2,3-c]pyridine (CAS 871819-21-5), molecular formula C8H6ClIN2 and molecular weight 292.50 g/mol, is a CATO reference standard with documented purity and traceability.
7-Chloro-4-iodo-3-methyl-1H-pyrrolo[2,3-c]pyridine (C8H6ClIN2) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine/iodine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
