Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 467.41 g/mol gives 3,7-Bis(diethylamino)phenothiazin-5-ium iodide distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 3,7-Bis(diethylamino)phenothiazin-5-ium iodide (CAS 439119-93-4), a certified reference material (molecular formula C20H26N3SI, MW 467.41 g/mol) for analytical method development and quality control.
Structurally, 3,7-Bis(diethylamino)phenothiazin-5-ium iodide (C20H26N3SI) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, iodine substitution. The molecule exhibits a degree of unsaturation (DBE) of 9.0, corresponding to approximately 9 ring(s) or double-bond equivalent(s). With a molecular weight of 467.41 g/mol, it falls into the moderately-high-molecular-weight range. 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.
