Chemical Structure
Description
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
5418-63-3 1,2,3,3-Tetramethyl-3H-indolium iodide 3H-Indolium, 1,2,3,3-tetramethyl-, iodide (1:1) 3H-Indolium, 1,2,3,3-tetramethyl-, iodide EINECS 226-526-2 3H-Indolium,1,2,3,3-tetramethyl-, iodide NSC 10498 2,2,3,4-Tetramethylbenzazolium iodide (CAS 5418-63-3), molecular formula C12H22NI and molecular weight 307.22 g/mol, is a CATO reference standard with documented purity and traceability.
5418-63-3 1,2,3,3-Tetramethyl-3H-indolium iodide 3H-Indolium, 1,2,3,3-tetramethyl-, iodide (1:1) 3H-Indolium, 1,2,3,3-tetramethyl-, iodide EINECS 226-526-2 3H-Indolium,1,2,3,3-tetramethyl-, iodide NSC 10498 2,2,3,4-Tetramethylbenzazolium iodide (C12H22NI) contains a nitrile group, 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.
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.
