4-(3-iodopyrazol-1-yl)-2-methoxypyridine (CAS 1350475-30-7) is a high-purity analytical reference standard with the molecular formula C9H8IN3O and a molecular weight of 301.08 g/mol.
The molecular framework of 4-(3-iodopyrazol-1-yl)-2-methoxypyridine (C9H8IN3O) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, 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. 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.
