Chemical Structure
Description
The molecular framework of 6-iodo-2,4-dimethyl-7,8-dihydro-6H-pyrazolo[4,3-b]azepin-5-one (C9H16IN3O) is characterized by 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. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
6-iodo-2,4-dimethyl-7,8-dihydro-6H-pyrazolo[4,3-b]azepin-5-one (CAS 2230522-03-7), molecular formula C9H16IN3O and molecular weight 309.15 g/mol, is a CATO reference standard with documented purity and traceability.
