The occurrence of 4,4',4'',4'''-(Porphyrin-5,10,15,20-tetrayl)tetrakis(1-methylpyridin-1-ium) iodide is closely related to a nitrogen-containing heterocyclic scaffold, a nitrile group, iodine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 4,4',4'',4'''-(Porphyrin-5,10,15,20-tetrayl)tetrakis(1-methylpyridin-1-ium) iodide (CAS 36674-90-5), a certified reference material (molecular formula C44H38N8I, MW 805.74 g/mol) for analytical method development and quality control.
4,4',4'',4'''-(Porphyrin-5,10,15,20-tetrayl)tetrakis(1-methylpyridin-1-ium) iodide (C44H38N8I) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, iodine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
