Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 529.24 g/mol gives Iodosulfuron-Methyl Sodium distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Iodosulfuron-Methyl Sodium (CAS 144550-36-7), molecular formula C14H13IN5O6SNa and molecular weight 529.24 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of Iodosulfuron-Methyl Sodium (C14H13IN5O6SNa) is characterized by a salt form, a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
