Chemical Structure
Description
The occurrence of 3,5-Diiodopyridine-2,6-diamine is closely related to a steroid core, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 3,5-Diiodopyridine-2,6-diamine (CAS 58372-55-7), a certified reference material (molecular formula C23H44N8O5, MW 512.65 g/mol) for analytical method development and quality control.
Based on its molecular formula C23H44N8O5, 3,5-Diiodopyridine-2,6-diamine contains a steroid core, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 512.65 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.
