Description

The occurrence of 905-97-5 3,3'-Diethylthiacarbocyanine iodide Benzothiazolium, 3-ethyl-2-(3-(3-ethyl-2-benzothiazolinylidene)-1-propenyl)-, iodide Benzothiazolium, 3-ethyl-2-(3-(3-ethyl-2(3H)-benzothiazolylidene)-1-propenyl)-, iodide (9CI) 3,3'-Diethyltrimethinethiacyanine iodide 3-Ethyl-2-(3-(3-ethyl-2-benzothiazolinylidene)-1-propenyl)benzothiazolium iodide NSC 93472 is closely related to a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, iodine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies 905-97-5 3,3'-Diethylthiacarbocyanine iodide Benzothiazolium, 3-ethyl-2-(3-(3-ethyl-2-benzothiazolinylidene)-1-propenyl)-, iodide Benzothiazolium, 3-ethyl-2-(3-(3-ethyl-2(3H)-benzothiazolylidene)-1-propenyl)-, iodide (9CI) 3,3'-Diethyltrimethinethiacyanine iodide 3-Ethyl-2-(3-(3-ethyl-2-benzothiazolinylidene)-1-propenyl)benzothiazolium iodide NSC 93472 (CAS 905-97-5), a certified reference material (molecular formula C21H34N2S2I, MW 505.54 g/mol) for analytical method development and quality control.

Based on its molecular formula C21H34N2S2I, 905-97-5 3,3'-Diethylthiacarbocyanine iodide Benzothiazolium, 3-ethyl-2-(3-(3-ethyl-2-benzothiazolinylidene)-1-propenyl)-, iodide Benzothiazolium, 3-ethyl-2-(3-(3-ethyl-2(3H)-benzothiazolylidene)-1-propenyl)-, iodide (9CI) 3,3'-Diethyltrimethinethiacyanine iodide 3-Ethyl-2-(3-(3-ethyl-2-benzothiazolinylidene)-1-propenyl)benzothiazolium iodide NSC 93472 contains a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, iodine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 505.54 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
