Chemical Structure
Description
As a certified reference material (CRM), 1,1,2,3-Tetramethyl-1H-benzo[e]indol-3-ium iodide meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
1,1,2,3-Tetramethyl-1H-benzo[e]indol-3-ium iodide (CAS 58464-25-8), molecular formula C15H16NI and molecular weight 337.20 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, iodine substitution, 1,1,2,3-Tetramethyl-1H-benzo[e]indol-3-ium iodide is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 337.20 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
