Chemical Structure
Description
The occurrence of 3H-Indolium, 2-[2-[4-(diethylamino)phenyl]ethenyl]-1,3,3-trimethyl-, chloride (1:1) is closely related to a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
3H-Indolium, 2-[2-[4-(diethylamino)phenyl]ethenyl]-1,3,3-trimethyl-, chloride (1:1) (CAS 6359-45-1), molecular formula C23H29N2Cl and molecular weight 368.95 g/mol, is a CATO reference standard with documented purity and traceability.
3H-Indolium, 2-[2-[4-(diethylamino)phenyl]ethenyl]-1,3,3-trimethyl-, chloride (1:1) (C23H29N2Cl) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine 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. 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.
As a certified reference material (CRM), 3H-Indolium, 2-[2-[4-(diethylamino)phenyl]ethenyl]-1,3,3-trimethyl-, chloride (1:1) 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.
