Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine/iodine substitution, 3520-43-2 1H-Benzimidazolium, 5,6-dichloro-2-(3-(5,6-dichloro-1,3-diethyl-1,3-dihydro-2H-benzimidazol-2-ylidene)-1-propenyl)-1,3-diethyl-, iodide Benzimidazolium, 5,6-dichloro-2-(3-(5,6-dichloro-1,3-diethyl-2-benzimidazolinylidene)propenyl)-1,3-diethyl-, iodide Benzimidazolocarbocyanine iodide, 5,5',6,6'-tetrachloro-1,1',3,3'-tetraethyl- JC-1 5,6-Dichloro-2-(3-(5,6-dichloro-1,3-diethyl-2-benzimidazolinylidene)propenyl)-1,3-diethylbenzimidazolium iodide Imidacarbocyanine iodide, 1,1',3,3'-tetraethyl-5,5',6,6'-tetrachloro- 1,1',3,3'-Tetraethyl-5,5',6,6'-tetrachlorobenzimidazolocarbocyanine iodide 1,1',3,3'-Tetraethyl-5,5',6,6'-tetrachloroimidacarbocyanine iodide 5,5',6,6'-Tetrachloro-1,1',3,3'-tetraethylbenzimidazolocarbocyanine iodide Bis(5,6-dichloro-1,3-diethyl-2-benzimidazole)trimethinecyanine iodide CBIC2 NK 1420 JC 1 is typically off-white to pale yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 665.32 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.
