Chemical Structure
Description
The molecular framework of 5505-16-8 3,5-Diamino-2,4,6-triiodobenzoate Benzoic acid, 3,5-diamino-2,4,6-triiodo- 3,5-Diamino-2,4,6-triiodobenzoic acid 4-14-00-01307 (Beilstein Handbook Reference) BRN 1466919 3,5-Diamino-triiodobenzoic acid EINECS 226-845-7 EC 226-845-7 (C7H5I3N2O2) 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.
5505-16-8 3,5-Diamino-2,4,6-triiodobenzoate Benzoic acid, 3,5-diamino-2,4,6-triiodo- 3,5-Diamino-2,4,6-triiodobenzoic acid 4-14-00-01307 (Beilstein Handbook Reference) BRN 1466919 3,5-Diamino-triiodobenzoic acid EINECS 226-845-7 EC 226-845-7 (CAS 5505-16-8) is a high-purity analytical reference standard with the molecular formula C7H5I3N2O2 and a molecular weight of 529.84 g/mol.
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.
