Chemical Structure
Description
The molecular framework of 2-Hydroxy-3,5-diiodobenzohydrazide (C7H6I2N2O2) is characterized by an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, iodine substitution, an aromatic ring system. 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
2-Hydroxy-3,5-diiodobenzohydrazide (CAS 89011-15-4) is a high-purity analytical reference standard with the molecular formula C7H6I2N2O2 and a molecular weight of 403.94 g/mol.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
