The molecular framework of 3071-70-3 Benzothiazolium, 3-ethyl-2-(7-(3-ethyl-2-benzothiazolinylidene)-1,3,5-heptatrienyl)-, iodide 3-Ethyl-2-(7-(3-ethyl-3H-benzothiazol-2-ylidene)hepta-1,3,5-trienyl)benzothiazolium iodide Benzothiazolium, 3-ethyl-2-(7-(3-ethyl-2(3H)-benzothiazolylidene)-1,3,5-heptatrien-1-yl)-, iodide (1:1) Benzothiazolium, 3-ethyl-2-(7-(3-ethyl-2(3H)-benzothiazolylidene)-1,3,5-heptatrienyl)-, iodide 3,3'-Diethylheptamethinethiacyanine iodide EINECS 221-342-9 3-Ethyl-2-(7-(3-ethyl-2-benzothiazolinylidene)-1,3,5-heptatrienyl)benzothiazolium iodide (C25H38N2S2I) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, iodine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
