Chemical Structure
Description
The molecular framework of tert-Butyl 3-(4-iodo-1H-pyrazol-1-yl)azetidine-1-carboxylate (C11H16IN3O2) 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.
tert-Butyl 3-(4-iodo-1H-pyrazol-1-yl)azetidine-1-carboxylate (CAS 951259-19-1), molecular formula C11H16IN3O2 and molecular weight 349.17 g/mol, is a CATO reference standard with documented purity and traceability.
