The occurrence of 1-Hydroxy-1-oxo-1lambda5-benzo[d][1,2]iodaoxol-3(1H)-one compound with pyridine (1:1) is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, iodine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
1-Hydroxy-1-oxo-1lambda5-benzo[d][1,2]iodaoxol-3(1H)-one compound with pyridine (1:1) (CAS 1380548-11-7) is a high-purity analytical reference standard with the molecular formula C7H5IO4C5H5N and a molecular weight of 359.12 g/mol.
The molecular framework of 1-Hydroxy-1-oxo-1lambda5-benzo[d][1,2]iodaoxol-3(1H)-one compound with pyridine (1:1) (C7H5IO4C5H5N) 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. 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).
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.
