1-Ethyl-4-((3-ethylbenzo[d]thiazol-2(3H)-ylidene)methyl)quinolin-1-ium iodide CAS 15941-82-9

Description

The occurrence of 1-Ethyl-4-((3-ethylbenzo[d]thiazol-2(3H)-ylidene)methyl)quinolin-1-ium iodide 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.

1-Ethyl-4-((3-ethylbenzo[d]thiazol-2(3H)-ylidene)methyl)quinolin-1-ium iodide (CAS 15941-82-9), molecular formula C21H21N2SI and molecular weight 460.37 g/mol, is a CATO reference standard with documented purity and traceability.

1-Ethyl-4-((3-ethylbenzo[d]thiazol-2(3H)-ylidene)methyl)quinolin-1-ium iodide (C21H21N2SI) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, iodine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; 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.
