Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 279.03 g/mol gives N,2-Dihydroxy-5-iodobenzamide distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies N,2-Dihydroxy-5-iodobenzamide (CAS 177348-38-8), a certified reference material (molecular formula C7H6INO3, MW 279.03 g/mol) for analytical method development and quality control.
The molecular framework of N,2-Dihydroxy-5-iodobenzamide (C7H6INO3) 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
