Chemical Structure
Description
The occurrence of 5-Iodo-1H-indazol-3-ol is closely related to an amide group, a hydroxyl group, an ether linkage, iodine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 5-Iodo-1H-indazol-3-ol (CAS 141122-62-5), a certified reference material (molecular formula C7H5IN2O, MW 260.03 g/mol) for analytical method development and quality control.
Based on its molecular formula C7H5IN2O, 5-Iodo-1H-indazol-3-ol contains an amide group, a hydroxyl group, an ether linkage, iodine substitution, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 260.03 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
